ERECTA SWITCH® by Compac Engineering

HVAC Level Switches

Condensate pan overflow prevention, cooling tower basin low-water cutoff and chiller reservoir alarms — in materials rated for treated water and glycol.

The problem

HVAC level sensing is mostly about preventing two failures: water where it should not be, and a pump running with nothing in it. Both are cheap to detect and expensive to miss — a blocked condensate drain damages ceilings, and a cooling tower pump that loses its basin damages itself.

Application examples

HVAC Condensate Pan — Overflow Prevention

Condensate pan overflow detection shuts the unit down when a blocked drain lets water rise in the pan, before it reaches the ceiling below. Shallow pans and side-only access make a side-mounted switch the practical choice.

Cooling Tower Basin — Low Water Cutoff

Basin low-water cutoff protects the circulating pump from running dry when make-up water fails to keep up with evaporation and blowdown.

Material selection

Every ERECTA SWITCH configuration is available in three materials. For this application the usual specification is Polypropylene (PP).
