Product Overview
The VWALVE Heat Recovery system captures waste heat from air compressors and converts it into usable hot water, delivering significant energy savings and reducing environmental impact. This complete heat exchange and pressurization station is designed as a single integrated unit for easy installation and operation.
The system recovers 65%-75% of the compressor’s input power that would otherwise be lost as heat. This recovered energy can be used for various purposes including process heating, space heating, and hot water supply. The intelligent temperature control system ensures optimal heat recovery without affecting compressor performance.
With rising energy costs and increasing environmental regulations, our heat recovery system offers an attractive return on investment, typically paying for itself within 1-2 years through energy savings.
Applications:
– Process Heating
– Space Heating
– Hot Water Supply
– Boiler Pre-heating

Temperature control Valve
A temperature-controlled three-way valve maintains the set temperature or flow in a piping system by adjusting the valve opening to mix two fluid streams or to route them along the same path. It can also effectively reduce water hammer when the temperature reaches the point at which the heat-transfer medium to the heat exchanger would be shut off. Control signal can be 0-10V or 4-20ma, and the valve body material can be stainless steel, canbron stell or brass. and vwalve brand or honeywell brand can be choose.
Plate Heat Exchanger
A plate heat exchanger is a new type of high-efficiency heat exchanger assembled by stacking a series of metal plates with a specific corrugated shape. Thin rectangular channels are formed between the various plates, and heat exchange is conducted through these plates. It is an ideal device for liquid-liquid and liquid-vapor heat exchange, featuring high heat exchange efficiency, low heat loss, compact and lightweight structure, small floor space, easy installation and cleaning, wide application, and long service life. Under the same pressure loss condition, its heat transfer coefficient is 3 to 5 times higher than that of a shell and tube heat exchanger, its floor space is only one-third of the latter, and the heat recovery rate can be as high as over 90%. vwalve brand or AlfaLaval brand can be choose.
Water Pump
A water pump is a machine that conveys or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid to increase the liquid’s energy. It is mainly used to convey liquids including water, oil, acid-base solutions, emulsions, suspensions and liquid metals, and can also transport liquid-gas mixtures and liquids containing suspended solids. Impeller pumps are adopted here, which transfer energy through the interaction between rotating impellers and water. vwalve brand or Grundfos brand can be choose.
Electric Control Module
The electric control system adopts the programmable logic controller (PLC), which is mature and reliable and can realize multiple functions as required. It is equipped with the touch screen dedicatedly matched for PLC, and supporting both Chinese and English display. The module mainly controls the start and stop of circulating water pumps and the automatic water make-up of the system, and simultaneously monitors the water temperature of the system. Other components are of the Schneider brand, featuring safety, reliability and wide application.
