TQ4200 Refrigerant gas, Infrared leak detection system. Universal voltage. Fault plus 3 alarm levels, VFC, audio and visual outputs, 4-20mA and Modbus output capable. C/W 16 output relay for zone control. A 5amp fused spur is required for installation.

APPLICATIONS 

• Retail Refrigeration  
• Refrigerant machinery areas 
• Air conditioning systems 
• Chilled water plants 
• Provision stores 
• IT Server Farms 
   
  The TQ4200 system has been 
  independently tested for inclusion in 
  the ECA scheme, as an Automated 
  Refrigerant Leak Detection System. 
  Mandatory under the F-gas 
  regulations for any refrigeration 
  plant containing 300kg of refrigerant. 
  The System has a modulated 
  broadband infra-red source to enable 
  the detection of CFC’s, HCFC’s and their 
  replacement, HFC’s allowing the 4200 
  to accurately monitor different gas 
  types simultaneously from a single 
  detection panel. 
  Gases detected can  include: R22, 
  R134A, R404A, R407C, R422D, 
  R507 and R32 with many more 
  available upon request; providing an 
  ideal solution when upgrading from 
  R22 applications. 

The TQ4200 is a compact, low cost solution to multipoint 
refrigerant gas leak detection. With optional expansion Relay card 
for individual channel alarms or zone control  
The system is available with a range of advanced ultra-stable infra
red gas analysers, which require NO CALIBRATION in service.  
Pre-programmed with several refrigerant gas types that can easily 
be changed in the field. 
With proven reliability and minimal maintenance the TQ4200 is 
designed for both industrial and commercial use e.g. 
Supermarkets, IT server farms, battery back-up rooms, food 
processing, storage & refrigeration, air conditioning and industrial 
cooling facilities.  
The TQ4200 Provides F-gas solutions for larger installations and 
exceptional leak detection for all applications.  The TQ4200 samples from up to 24 points and analyses the gas 
sequentially from each point. Each gas sample is conditioned by 
passing it over particulate filters and water catch pots, to ensure that 
the reliability of the infra-red analyser is not compromised. Accurate 
multiple calibration allows sampling from independent refrigeration 
plants containing different refrigerant gases. 
The system requires a universal 100-250 Vac power supply rated at 
5 amps. Connection of the sample lines completes the self
contained operation.
