Profile: Brenway Manufacturing Company specializes in the production of stainless steel chillers for many industries including breweries, dedicated drinking water, and environmental injection molding. We provide a closed loop, packaged chiller designed specifically to cool and recirculate a clean coolant at a constant temperature, pressure & flow. These chillers are ideal for all installations where a dependable source of clean cooling water is not available. The storage-type cooling tank (called a chiller barrel) is a non-pressurized, sealed tank which prevents coolant evaporation or fouling, and is supplied with a liquid level gauge & fill port. The pump recirculates the coolant at a temperature, pressure & flow, and is available with a manually adjustable bypass valve. Non-pressurized storage-type cooling tank is constructed of a welded #304 stainless steel shell, with a #316 annealed stainless steel or copper fused immersion coil evaporator. Although these chiller barrels are non-pressurized, they are pressure tested to assure safety & reliability, and are supplied with a pressure safety relief valve, supplied with a drain connection & insulated with closed cell thermo-elastomer with an R factor of 3.7. Our chillers also utilize the storage-type cooling tank with both the stainless steel, or stainless steel and copper fused immersion coil evaporator in clear ABS hard plastic for a fraction of the cost of stainless steel.
