NOTE: • Sani-Matic standard is to design steam heating applications for 50 psi steam Installations where the plant supplied steam is more than 50 psi may require a pressure reducing valve (PRV) installed (by others)
The Electric Heater to Maintain Temperature option removes the direct steam injection assembly from the standard system and replaces it with an electric immersion heater within the recirculation system The heater is sized to maintain temperature of a cleaning cycle step – as such, the incoming water temperature should be equal to or greater than the highest desired cleaning cycle water temperature required The following components are added:
• One (1) Hygienic heater housing assembly • One (1) Inline electric immersion heater − Duty: Temperature maintenance only
− Material: 316Lss (wetted) − Connections: Tri-clamp − Size: See Table 9: Electric Heater Data − Protection: High temperature thermocouple
