Our product line consists of circulating water and heat-transfer oil temperature control systems, portable and central chillers, pump tanks, cooling towers, blown film coolers, cold climate coolers, engineered and pre-engineered control panels, maintenance products, and custom designed/engineered systems.
Circulating heat-transfer oil temperature-control systems with a temperature range to 650F incorporate a cool oil reservoir that eliminates thermal shock associated with in-line shell and tube heat exchanger.
Added to the heat-transfer oil, the cleaner dissolves and suspends sludge that can reduce flow and heat transfer.
Since the heat capacity and viscosity of heat-transfer oils is substantially different from those of water, this will often require redesign of the whole cooling system.
Oil is a less severe cooling medium than water, as most heat-transfer oils have less than half the heat capacity of water.
Roll-heating and cooling control systems use high-temperature water and heat-transfer oils for temperatures from 200 to 700 F.
