Why is CBS Isothermal -190C Air Storage LN2 Freezer preferred?
Temperature Uniformity. CBS Isothermal provides excellent temperature control throughout the freezer, from -190C at the bottom of the freezer to the top, right below the lid.
Safety. Storage in liquid nitrogen can make vials shrink. This may cause liquid nitrogen to seep into the vials, which on re-warming, expand and subsequently explode as nitrogen vaporizes inside the vials. Dry storage eliminates this possibility. Also, the Isothermal design provides added user safety by eliminating contact with or splashing of liquid nitrogen.
Cross Contamination. Studies have shown that viral, bacterial and fungal pathogens can survive after suspension in liquid nitrogen. Infected samples can cross contaminate other samples in the same liquid nitrogen tank. Dry storage eliminates the possibility of cross contamination.

Experimental Study on Heat Recovery from Continuous Blow down Water And Reduc...IJERA Editor
Waste heat is heat which is generated in a different process i.e by combustion of fuel, by chemical rection. The
important of heat is its value not quality. The planning of how to recover this waste heat depends in part on the
temperature of waste heat gases. The energy lost in waste heat can not be fully recovered but maximum quantity
of heat can be recovered and loss is minimized. Generally higher the temperature, higher the quality and then
more cost effective is the heat recovery.
Lots of heat is lost by blow down so it is necessary to recover this heat by addition of heat exchanger in
between this process. So this waste heat could be utilized to heat boiler water before going to de-aerator. By
applying this process we can easily reduce loss of heat and heat required to heat boiler water is reduced. Also
this blow down water we can utilized as feed water so consumption of feed water is also reduced. But this blow
water we cant utilized as boiler water because we rejected due to high TDS. If we utilized then TDS level in
boiler is increased. So it is beneficiary to use this at the starting of demineralization.

As operating temperatures of mechanical equipment and piping systems drop, increased diligence must be exercised to optimize the insulation system’s performance and mitigate risks of future deterioration. When specifying and installing an insulation system for pipes or equipment operating at refrigerant temperatures (e.g. -70°F to 32°F) cutting corners or rationalizing compromises is imprudent since the operating costs and risks far outweigh any reduced capital costs; and it is important to note that the best systems are typically not the most expensive systems.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Properties
Glythermin NF is a clear, colourless liquid with a faint odour and is based on
ethylene glycol.
Glythermin NF is miscible with water in all proportions. Its mixtures with
water protect against frost at temperatures of down to – 50 °C, depending
on their concentration, and lengthen the life of the installations that they
protect.
Mixtures of Glythermin NF and water do not demix.
The corrosion inhibitors contained in Glythermin NF allow the metals nor
mally used in heating, refrigeration and mixing installations to be reliably
protected for long periods against corrosion, ageing and fouling.
Glythermin NF has excellent stability at high temperatures and prevents the
formation of harmful deposits on hot metal surfaces (at temperatures of up
to 200 °C) at watt densities as high as about 40 W/cm2. It thus
helps to avoid overheating at heat-transfer surfaces and the formation of
deposits in the circuit.
Glythermin NF does not contain any nitrites, phosphates or amines.
Miscibility Glythermin NF is miscible with all commercial heat transfer fluids based on
ethylene glycol.
Applications
The concentration of Glythermin NF should be at least 20 % v/v. in water of
drinking quality (100 mg/kg Cl¯ max.). However, the protection against frost
deteriorates if the Glythermin NF concentration is higher than 58 % v/v.
Temperature stability Sustained temperatures higher than 140 °C cause premature ageing of
the heat-transfer liquid, but brief exposure to temperatures higher than
140 – 200 °C can be tolerated if the liquid is subsequently cooled. At temper
atures above 200 °C, the heat-transfer liquid commences to undergo chem
ical change, with the result that the dependability of the installation may be
endangered. A blanket of nitrogen is recommended to lengthen the life of
the heat-transfer liquid if the sustained operating temperature is higher than
110 °C.
The anticorrosion effect of a mixture of Glythermin NF and water is evident
from the following table, which lists the results of ASTM D‑1384-70
corrosion tests.

3. Average change in weight of coupons in g/m2
Material Glythermin NF/ASTM – Water 1 : 2
Copper (F-Cu) – 0.1
Soft solder (L Pb Sn 30) ± 0.0
Brass (Ms 63) – 0.1
Cast iron (GG 25) ± 0.0
Steel (H II) – 0.2
Cast aluminium (G AlSi6Cu4) – 0.3
The outstanding anticorrosion properties of Glythermin NF/water mixtures
have also been demonstrated in high-temperature corrosion tests on
cast iron (GG 25) and cast aluminium (G-AlSi10Mg) coupons subjected to
the flow and heat-transfer conditions relating to watt densities of up to 40
W/cm2.
In order to maintain effective protection from corrosion, the concentration of
Glythermin NF must not be allowed to fall below 20 % v/v. The correspond
ing protection against frost is effective at temperatures down to – 9 °C.
Concentrations lower than 20 % v/v are insufficient and incur the risk of
corrosion.
If Glythermin NF is run into existing installations in which only water has pre
viously been circulated, it should be noted that the rust in these systems
greatly increases the effective area of contact with the heattransfer fluid.
It thus binds the inhibitors contained in the Glythermin NF, with the conse
quence that their effective concentration may be reduced to such an extent
that the protection against corrosion is impaired.
For this reason, the rust in these installations should be flushed out to
the utmost extent before the Glythermin NF is run in. In particularly
severe cases, pickling with subsequent neutralization of the acid is
recommended.
After they have been emptied, installations that have been run temporar
ily with Glythermin NF must be thoroughly flushed several times to ensure
that all residual traces of the product are removed, because any product
residues may give rise to increased corrosion.
Mixtures of Glythermin NF and water do not attack the sealants normally
used in heating systems. The following list of sealants, elastomers and plas
tics that are resistant to Glythermin NF/water mixtures has been
compiled from experimental results, experience, and the literature.
Examples of sealants are Fermit® and Fermitol® (registered trademarks of
Nissen Volk GmbH, Hamburg) and hemp.

4. An important point to note is that the performance of elastomers is gov
erned not only by the properties of the rubber itself, e. g. EPDM, but also
by the nature and amount of the constituent additives and the vulcaniza
tion conditions. For this reason, it is recommended that their resistance to
Glythermin NF/water mixtures is checked by performance tests before these
elastomers are taken into use for the first time. This applies particularly to
elastomers intended as membranes for expansion tanks as described in
DIN 4807.
Seals based on 70 EDPM 281* have been shown to be resistant to mixtures
of Glythermin NF and water at temperatures of up to 160 °C, and flat-flange
gaskets such as REINZ-AFM 34** or Centellen 3820 based on aramid and
special NBR*** have been shown to be resistant at temperatures of up to
200 °C.
In some cases, the low surface tension of Glythermin NF/water mixtures
may be responsible for leakage if the sealing strips have been produced
from polytetrafluoroethylene (PTFE). Likewise, the addition of Glythermin NF
in heating systems may allow latent leaks to be detected, because the
resultant Glythermin NF/water mixture has better wetting power.
If the leakage cannot be prevented by tightening the connections, the
system must be drained. The seals must then be replaced, and the connec
tion must be rechecked to ensure that there is no leakage. It is important
that all the connections with renewed seals are retightened after the system
has been restarted and brought to the maximum operating
temperature.
The procedure for filling installations with forced circulation is to run in about
two-thirds of the requisite amount of water first of all.
The Glythermin NF should then be added and the system topped up with
the remainder of the water. The Glythermin NF and the water become
completely mixed after the circulation pump has been run for several hours.
The Glythermin NF and the water must be completely mixed together before
they are filled into installations with natural circulation.
After the installation has been filled, the Glythermin NF content should be
checked by measuring the density of the mixture with a hydrometer (see den
sity/concentration diagram). It must be ensured that the hydrometer is free
to float in the cylinder.
The Glythermin NF content can also be determined by measuring the refrac
tive index with a refractometer. Values for the density and refractive index of
Glythermin NF/water mixtures are presented in the following table.

5. In view of the specific properties of Glythermin NF, the following instructions
must be adhered to for ensuring long-term protection.
1. The installations must be designed as closed circuits, because the entry
of atmospheric oxygen causes the inhibitors in Glythermin NF to be
consumed more rapidly.
2. Flexible-membrane expansion tanks must conform to DIN 4807.
3 Silver or copper brazing solder should preferably be used for joints. If
flux is used that contains chlorine compounds in conjunction with tin-
lead solder, it is important that all traces are flushed out of the system,
because increased chlorine levels in the heat-transfer fluid can cause
corrosion.
4. The only flexible connections that are permissible are hoses,
preferably metal, that do not permit the diffusion of oxygen.
5. The surfaces of heat exchangers, tanks and tubes exposed to the heat-
transfer liquid must not be galvanized, because zinc is detached by
water/glycol mixtures.
6. It must be ensured that no external voltages can be applied between
parts of the installation that come into contact with the Glythermin NF
solution, as otherwise corrosion may occur.
7. The layout of the tubes must ensure that circulation cannot be
disturbed by gas pockets or deposits.
8 The level of the heat-transfer liquid must never be allowed to fall below
the highest point in the system.
9. Dirt and water must not be allowed to enter the installation or its com
ponents during assembly and before filling. After assembly has been
completed and the connections have been soldered, the system must
be flushed to remove any foreign matter (swarf, fluxes, packaging
residues, sawdust, etc.) and assembly aids.
10. It must be ensured that no air pockets remain in the installation after it
has been filled.
It is essential to eliminate gas pockets, because their collapse following
a drop in temperature would give rise to a vacuum and thus cause air
to be sucked into the system.
11. In order to ensure that there are no obstructions to the flow of the heat-
transfer liquid, the in-circuit fillers must be cleaned within 14 days, at
the latest, after the installation has been charged and taken into opera
tion for the first time.
12. If leakage or other losses occur, the heat-transfer liquid in the system
must be replenished with an aqueous Glythermin NF solution of the
same concentration. In cases of doubt, the Glythermin NF content must
be determined.
Storage stability Glythermin NF has a shelf life of at least three years if it is stored in her
metically sealed containers. We do not recommend storing it in galvanized
containers, because zinc is attacked by mixtures of glycol and water.
Packaging/form of delivery Glythermin NF is supplied in road tankers and in 230 kg non-returnable
metal drums.
Disposal Glythermin NF spills must be taken up in an absorbent binder and
disposed of in accordance with regulations.
If the pertinent local regulations are observed, Glythermin NF can be
disposed of by special treatment, e. g. combustion in an authorized
incinerator.

Ecology Glythermin NF is biodegradable. If it is run with the appropriate care into
an acclimated water treatment plant, it will not impair the efficiency of the
activated sludge.
Safety
Handling Glythermin NF may not be used in plants in which there is a possibility that
the heat-transfer fluid may come into contact with foodstuffs or potable
water. We would recommend using Glythermin P 44 for this type of applica
tion, because it is based on propylene glycol and poses no hazard to health.
The usual safety and industrial hygiene measures relating to chemicals
and flammable liquids must be observed in handling Glythermin NF. The
information and instructions given in our Safety Data Sheet must be strictly
observed.
Precautionary measures Avoid skin contact.
Safety Data Sheet A Safety Data Sheet has been drawn up for Glythermin NF along the lines
laid down in the EEC Guideline 91/155/EEC.

Example
By how many litres does the volume of V0 = 80 litres of a 30% v/v mixture
of Glythermin NF and water increase when it is heater from t0 = –10 °C to t1
= + 90 °C?
∆t = t1–t0 = + 90 – (–10) = 100 °C, tmean = t0 +
βmean (from curve for 30% v/v mixture) = 51 · 10–5
∆V = βmean ∆t · V0 = 51 · 10–5
· 100 · 80 = Increase in volume of 4.0 litres
