The HT100, HT200, and HT300 High Side Floats (Float Drain Regulators) are typically used to drain condensers to chillers, recirculators, controlled pressure receivers, or flooded evaporators; to drain hot gas supply mains; or to drain liquid condensate from heat reclaim coils.

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.
