RefTech Ltd is experienced in the design and installation of various building services piping systems including hot and chilled water using carbon or stainless steel pipes as well as crimped piping systems. Our advanced spray chilling system design provides low weight loss with efficient water management.
Secondary refrigerants are used in for many special cooling applications. The most common secondary refrigerants in use are propylene glycol, ethylene glycol and water. A typical application for secondary refrigerants is a chiller package or a central compressor room connected to a high-efficiency heat exchanger. These designs significantly reduce the operating refrigerant charge yet allows for a large number of areas and cooling devices to be serviced. The use of chilled water to provide cooling in medium and high-temperature applications is gaining attention, primarily in processing areas.
