Imperial Tool 535C Kwik Charge Liquid Low Side Charger

Eliminated my concerns of possibly damaging a compressor if I attempted to add refrigerant too fast. My piece of mind was well worth the price.

Works Great

This device takes the liquid Freon and passes it through an orifice; the pressure drop across the Orifice causes the Freon to gas off.A compressor pumps vapor and does not pump liquid without damaging the compressor. Hence the use of this device.So do yourself a favor and get this device, It allows you to charge 410A and other freon blends that must be in a liquid state to be charged.Gases enter the low side of the compressor in a gaseous state without separating the freon blends mixture rate.The purpose of adding Freon on the low side is the low side line has a lower pressure and depending on the temperature outside your drum pressure might not be enough to overcome your high-pressure line.This quick charge those three things for you:1. It allows you to add Freon on the low side and cut your charging time down.2. It mitigates the higher head pressures on the liquid line versus drum pressures.3. It keeps you from damaging the internal components of the compressor.With this device attached to your gauge manifold on the center port you simply turn your freon drum upside down to feed liquid freon to this “Kwicharge” device. The liquid freon turns to a gaseous state and enters the manifold; routed to the low pressure “Big” line, (use the blue hose side of manifold). The gas feeds into your compressor which then compresses it through the condenser, the condenser cools it and turns it back into a liquid to feed the evaporator coil. And there you go HVAC 101. Hope this helps you.

Worked great!

good for service. takes too long on weighing in a full charge on a larger system.

Best liquid refrigerant charging metering device on the market.

This arrived on time. It is used when filling an air conditioner with 410a. Aaac Service Heating and air conditioner repair in McDonough recommend these. It is slow to charge an a/c but that is what it's for. Works like the one I lost.

Very handy tool!
