High Pressure Metering

ECO MIX

Polyurethane Processing Equipment

The strong international focus that has been placed on greenhouse gases and gases which are hostile to the ozone layer, has led ISC to deep and strong efforts for the development of efficient and environmentally friendly foaming processes.

Today, ISC puts a lot of efforts to helping customers in shifting their equipment for hydrocarbons-blown foams all over the world, with a wide range of available metering systems dedicated to this process.

The blending unit “Ecomix” is an innovative, simple, and precise mixing system that allows the use of new generation blowing agents, including hydrocarbons, only when necessary. Combined with other complementary equipment it helps to optimize times and methods in the production process.

Equipment Packages

The ECOMIX device is an automatic system which permits to meter and mix by keeping a constant ratio between Polyol and ecological blowing agents (HC) through high accuracy control systems by selecting the quantity,

High efficiency dosing pump for pure Polyol, coupled to a motor at variable speed by means of frequency converter.
Safety pressure gauge at Polyol dosing pump feeding.
Safety pressure gauge in suction to the HC blowing agent metering pump.
HC blowing agent metering pump diaphragm type coupled to a frequency converter-driven motor for ratios/deliveries setting and change.
Safety pressure gauge at the HC blowing agent metering pump feeding point.
Static mixer to get a homogenous blend.
Polyol flow control made of volumetric flowmeter.
Flowmeter for HC blowing agent with high accuracy.

Automatic valves for recycle pressure adjustment on Polyol and HC blowing agent line.
Pressure balance system to ensure a perfect blending.
Continuous monitoring of the blend via analog PLC control.
PLC Siemens S7-1200 series for data processing.
HMI type Siemens KTP 700 series for settings and alarm visualization.
Frequency converter for POLYOL and HC Blowing agent pump motors.
Ethernet connection for production data facility
