Heat exchangers are used In a variety of applications to transfer heat from a heat source to water in residential or commercial pools, spas, or hot tubs. Pool temperatures are maintained at the desired level by running a heating loop through the heat exchanger using services fluids heated by boilers, heat pumps, or renewable heat sources such as solar-heated or geothermal water. Stainless steel is often nominated as the heat transfer material of choice for pool heat exchangers due to its durability, affordability, availability, [...]

Brazed plate heat exchangers are made by brazing a stainless steel plate pack using a material such as copper to create a strong inter-plate bond — this seals the unit permanently and creates unique operational challenges with regards to cleaning and maintenance. This style of heat exchanger is compact and efficient, leading to wide use in HVAC, hydronic heating, steam heating, as well as industrial applications with a wide variety of process fluids. These units utilize relatively narrow flow channels to promote efficient [...]

Sanitary pumps are specified in hygienic manufacturing industries where product specifications and regulations are at their tightest, and the slightest contamination is considered unacceptable. In order to maintain this level of sanitation, not only must the proper pump be specified, it must also be maintained and cleaned correctly throughout its service lifetime. Small sanitary pumps in the food & beverage, as well as pharmaceutical industries, will have specific manufacturer guidelines for cleaning in addition to general best practices for maintaining the requisite level of [...]
