Point-of-use eyewash heater

The Eemax SPEX100T EE is an electric tankless water heater configured for eyewash stations. It runs on 277 V AC single-phase power and draws 36 A at 10,000 W. The unit activates at a minimum flow of 0.2 gpm and delivers up to 3 gpm. Water temperature is adjustable between 70 and 90 degrees F for safe, tepid output.

Indoor commercial facilities only

This model suits indoor commercial sites that have 277 V single-phase service and need a compact eyewash heater. The 10.75 in height, 5.25 in width and 3 in depth fit tight mechanical spaces. Facilities without 277 V supply, or installers needing higher flow rates for multiple fixtures, should consider other solutions.

277 V single-phase power requirement

The heater operates exclusively on 277 V AC single-phase current at 36 A. A compatible electrical service and dedicated circuit are mandatory for installation. Without this exact voltage and phase configuration the unit will not function.

Questions about this item

What cold-water inlet size does the SPEX100T require?

The unit uses a 3/8 in cold inlet, so plan piping or adapters to match that connection.

What electrical supply is needed and what wiring mistake should be avoided?

It needs a 277 V AC single-phase circuit rated for 36 A; the common error is using a lower-voltage or undersized breaker.

How often should the inlet filter be checked on this model?

Inspect and clean the inlet screen at least once a year, or more often in hard-water areas, to maintain the 0.2 gpm activation threshold.
