M Series:
Water Heater/Pumping Stations

The M Series incorporates the same basic unit as the D Series, plus a centrifugal pump for recirculating hot water to the customer's holding tank. Water heater, pump and electricals are mounted on a rugged steel skid. Electrical control box includes starters for each heater/pump section.

This system is designed for applications where there is a need for a large quantity of water in a short time period, such as when multiple ready mix trucks need to be loaded quickly. Using a customer-supplied vented water tank, water is recirculated by the pump into the tank, achieving the desired water temperature. Standard primary electricals are 230/3/60, 460/3/60, 230/1/60
