This document is a product presentation for Danfoss TE 5-55 thermostatic expansion valves. It provides information over 36 pages on the features and operation of the TE 5-55 valves. The valves have a wide capacity range from 3 to 85 tons and are compatible with most refrigerants except R410A. They control the flow of refrigerant into an evaporator by maintaining a constant superheat to match changes in cooling load.

TE 5-55 Thermostatic
Expansion Valve
The TE TEV will control and maintain
the required amount of refrigerant
injected into the Evaporator.
Doing this by keeping the Superheat
Constant where the sensor is
mounted on the suction line
(In a constant load scenario)

Function of the TE 5  55
The TEV will try to keep a constant superheat at a
constant load situation
If there is a change in load the TEV will open more at
increasing load and open less at decreasing load,
and again try to keep a constant superheat
The opening degree is decided by a balance
between the opening force and the closing forces
• Pressure in the Power element is the opening force
• Pressure from the refrigerant is a closing force
• Pressure from the spring is the other closing force

Adjusting the TE 5  55
In most cases it is not necessary to
adjust the TE 5 to 55's
But if you have the experience, that
for this or that kind of system it will
be an improvement, then do it

To be able to accurately inject
the amount of refrigerant required,
into the evaporator.

WHEN ?
Every time there is a refrigeration
system then one for each evaporator
(If not another means of throttle
devise is used)

HOW ?
By mounting the Thermostatic Expansion Valve
in the correct way in the refrigeration circuit
and adjust it accordingly if necessary.

Adjust if you want to optimize
evaporator performance
(If it is "too stable", excessive
static superheat)
Adjust if the TEV is hunting
(If it is "not stable", not enough
static superheat)
