Geo Therm Ltd is a UK based inspection and services
company, founded in 2002. Since this time we
have supported numerous companies, SME’s and
individuals, with the provision of our thermal imaging
and ultrasound condition based monitoring (CBM)
services and inspections, including the supply and
installation of infrared inspection windows and
the Delta T Alert™ temperature probe. Locating
heat and sound deficiencies in LV/HV electrical,
mechanical, pneumatic and hydro-carbon systems
all non-invasively. We are ISO 9001, Safe Contractor
accredited and FPAL registered.

Ultrasound Surveys
‘Ultrasound - the high
frequency noise in
HV systems indicating
partial discharge’
We install and configure Partial Discharge (PD) sensors mounted
to HV switchboards monitor for PD remotely from anywhere in
the world. We utilise handheld ultrasonic probes to detect high
frequency noise escaping from compressed air and hydro-carbon
lines. We are also capable of detecting worn pump and motor
bearings using this technology.
Our ultrasonic devices detect:
• Arcing, tracking and corona in HV electrical distribution switchgear
• Escaping gases, passing valves, cavitation, vacuum leaks, steam
trap mal-functioning in industrial piping
• Poor lubrication and bearing issues in mechanical and
reciprocating machinery.
Compressed Air Leak Detection
We use the latest ultrasonic equipment to pin-point the smallest
compressed air leaks, even in the nosiest environment. Compressed air is
considered the forth utility, typically this vital resource is undermanaged
and inefficient, representing a substantial energy cost component to any
manufacturing or process facility.
The benefits of air leak detection include:
• Immediate reduction of electricity
costs upon leak identification and repair
• Reduction in Carbon foot print
• Improves workplace safety
• Improves compressor reliability and longevity. ‘Air is free - until it’s compressed’

2. Infrared (IR)
Window Installation
‘Installation of IR windows is the safest
means to view inside electrical cabinets
without having to shut the system down’
Thermal
Imaging Surveys
We retro-fit IR inspection windows to remove the hazards
relating to inspecting energised electrical distribution
equipment. Installation allows safe viewing without
opening panels and exposing personnel to the potential
of electrocution and arc flash. We supply and install all
types of IR windows (IRISS, CorDEX, FLIR and FLUKE),
because we know accessing LV and HV equipment for
regular PM needs come at a risk.
The benefits of IR windows include:
• Improved survey thoroughness, frequency and
access on equipment that would otherwise
have been missed
• Installation removes the need to open or power
down equipment
• Able to withstand 11kVA arc flash. IP65/IP67 rated
for outdoor use
• Inexpensive, short installation time, clear view
crystal or polymer lens, available in bespoke sizes
• Installation removes high risk behaviours
• Maintains closed and guarded condition, reduced
manpower to survey
• Successfully used in the processing and manufacturing
industries, food sectors, offshore industries and
utilities to help maintain operational efficiency and
employee safety.
‘The human eye cannot see heat until a component is glowing cherry red’ Quality Services Without Compromise
Geo Therm Ltd perform infrared (IR) thermographic
surveys to detect and monitor extreme temperatures
in electrical distribution and mechanical equipment to
prevent downtime in industry, identifying hot spots in
vessel engine rooms and energy losses in commercial
and domestic buildings. Improving heating deficiencies,
effectively directing maintenance strategies to
successfully prevent asset downtime, safety and
compliance with regular preventative maintenance (PM)
needs, vessel class prerequisites and insurance risk
assessments against fire and consequential losses in:
• Production and manufacturing facilities
• Refineries, offshore oil gas and maritime industries
• The nuclear and energy sectors
• The built environment: domestic and commercial
buildings, coldstores and warehousing.
Delta T Alert™
We supply, retro-fit and configure the
Delta T Alert™ wireless system, the latest self-
contained remote temperature-monitoring
sensor available to-date. The Delta T Alert™
monitors and alarms the end user to any
pre-programmed temperature deviation,
indentifying the early onset of potential failure.
Benefits of the Delta T Alert™ include:
• Alarm - audio, visual and email allowing
immediate notification as issues arise
• Reporting - up to 8 readings per day for
trend analysis
• On demand status reports
• Provides standalone, remote temperature
monitoring of vital systems.
‘Heat is the early precursor to
equipment failure, monitoring elevated
temperatures in vital systems will direct
maintenance attention fast’
IR Gas Find Surveys
We utilise the optical infrared gas-find camera
to non-invasively monitor fugitive gas emissions
within petrochemical refineries, offshore process
platforms and storage facilities. Scanning for
hydro-carbon leaks at a safe working distance;
targeting high risk process systems to remove
risks of polution and fire.
IR Gas Find benefits include:
• Locating leaking gasket joints, valves and storage
vessels holding volatile products
• Improve upon site best practices
• Maximise productivity and profits
• No disruption to operations
• Environmental and regulatory compliance.
