The HD101 Defrost Drainer, a variation of the HT100 high side float, has an adjustable vent valve bypass to fine-tune individual systems which may experience evaporator defrost gas binding. It is designed as a liquid condensate drain for an evaporator during hot gas defrost. It drains liquid while preventing most hot gas from flowing to the suction line. This process saves energy by eliminating artificial loading of the compressor.
