A custom vacuum pump manufacturer that serves many industries contacted Tempco regarding a special project. The project required that the water within a reservoir tank be maintained at a minimum temperature of 40°F. The required wattage for the insulated tank was calculated based on a minimum ambient temperature of 20°F. The customer required several unique design features:

• The heater must be able to be removed during service without draining the tank.
• Due to space constraints, the heater must fit into an existing 1.25” NPT fitting hole.
• A moisture-resistant housing for the heater is necessary.
