Refrigerant Leak Detector Testing RLD400

Detects all commercially available HFC, HFO, HC, HCFC, and CFC Refrigerants in mobile and stationary air conditioners, refrigerators, chillers and heat pumps

Stopping Refrigerant Gas Leaks will keep your AC system running at peak efficiency, save money and even improves a vehicle’s gas mileage.

Why look for refrigerant leaks?

There are three reasons to detect and repair leaks of refrigerant gases from stationary and mobile air conditioners, refrigeration systems and heat pumps:

1. Leaks allow air and moisture to enter an A/C system or chiller. Moisture can react with refrigerant to form corrosive acids and sludge that can damage a compressor, plug up orifice tubes, and/or eat pinholes in evaporators and condensers.

2. Refrigerant is expensive. It may seem cheaper to keep recharging your system with refrigerant than fix a leak—but it isn’t in the long run. And A/C systems and chillers that aren’t fully charged won’t cool efficiently and thus waste money (electricity-powered systems) or fuel (vehicle systems).

3. Most refrigerants deplete the ozone layer that blocks the Sun's harmful ultraviolet radiation. In the U.S., the Clean Air Act of 1990 and later amendments require owners or operators of refrigeration and air-conditioning equipment with refrigerant charges greater than 50 pounds to repair leaks within 30 days when those leaks result in the loss of more than 15% (comfort cooling) or 35% (commercial cooling) of the charge over a 12-month period.

New proprietary semiconductor sensor detects many new ozone layer-friendly refrigerants approved under the U.S. EPA's Significant New Alternatives Policy (SNAP)
