Refrigerant Leak Detector for HFC, HFO, HC, HCFC, CFC RLD440

Technologically Advanced Dual Mode Gas Leak Tester

General Tools RLD440 Refrigerant Leak Detectors are used in the maintenance of mobile and stationary air conditioners, refrigerators, chillers, and heat pumps.

Dual Mode Leak indication combines UV LEDs to visually detect leaks of fluorescent dye injected in A/C systems with a proprietary semiconductor sensor used to gauge and display the size of the leak

A technician would first use the patented UV light emitting diodes (LEDs) on the front of the instrument to detect and pinpoint any leaks of fluorescent dye injected into the system. Then the technician would then use the proprietary semiconductor sensor at the end of the probe to gauge and display the size of the leak.

General Tools Refrigerant Leak Detectors have a long-life sensor is designed to sense all commercially available HFO, HC, HCFC and CFC refrigerants, including the more difficult to detect ozone-friendly HFC refrigerants approved under the U.S. EPA’s Significant New Alternatives Policy (SNAP).

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.
