Production rate
120/1900 kg/h
The AC-C series includes water/air batteries for the cooling of blown film and agri-film extrusion lines with production included between 120 and 1900 kg/h.
The range is available in two versions:
• MONO for OBC cooling.
• TWIN, with stacked batteries, for OBC and IBC cooling.
Our batteries can be supplied to replace existing ones by operating with inlet water 5°C higher than current solutions on the market, thus requiring a lower cooling input.
External structure is made of galvanized sheet metal and painted with fine polyester powders (RAL9002 and RAL7037) with effective resistance to corrosive agents.
Internal structure is made of galvanized sheet metal.
All components are sealed and riveted to ensure excellent sealing.
The air connections are of the OK type (JACOB type on larger sizes), sealed and welded to the internal frame.
A pressure gauge is installed externally to survey and monitor pressure of the water entering the battery.
Each battery is supplied complete with adjustable antivibration feet for flat positioning even on surfaces
with a slight difference in level.
The high-efficiency exchanger has a large exchange surface and is made with aluminum fins and copper tubes. The larger surface area allows the speed of the air to be limited without the use of a droplet separator: the oversizing of the exchanger also allows the electrical consumption of the process fan to be reduced.
The exchanger is designed to work with cold water at temperatures just 3°C lower than the required outlet air temperature: this allows for significant energy savings on chilled water consumption compared to more conventional solutions.
Air temperature reading and regulation system can be easily set by the operator on an electronic control protected by an IP65 transparent door.
The control allows the adjustment of the electronic 3-way valve to keep the outlet air temperature constant.
• Pressure gauge to survey water pressure
• Easy-removable filter for maintenance operations
• Electronic, modulating 3-way valve
• NTC probe to survey the inlet/outlet water temperature
