Pneumatic CNMC-E2 polyurethane spraying machine 17MPa

Description of CNMC-E2 polyurethane spraying machine:

The new CNMC-E2 air driven proportioning unit is of an advanced and compact design. It is specially aimed at the applications of polyurethane foam in place. Its particular configuration facilities easy access to all its components, simplifies the control functions ad significantly reduces the maintenance work.

Primary Heating System

The primary heating system consists of two separate independent block heaters with no seals. Each heater heating elements that supply a total power of 3000 W with the necessary control and safety features for the accurate and reliable performance of the system. The special design of the heaters allows for a DT of 30º C and enables it to reach application temperatures of 70º C in normal environmental conditions.

Proportioning Pumps

The system is including two positive displacement piston pumps, driven by a pneumatic motor. The proportioning pumps are manufactured from high hardness tempered aluminium and a special treatment that offers a low coefficient of friction, a high level of lubrication, and an increased level of wear resistance. The system includes a common guide system that ensures dynamic stability guaranteeing the correct alignment of the pump group and extending the life of the packing seals.

Recirculation System

Recirculation of the two components allows a faster achievement of the preset temperatures at the heaters before starting to spray and during temporary shutdowns.

Hose Heating System (OPTIONAL)

The hose heating system is designed with 1000W each 15 meters that allows the heating of up to 90m. of hose. The system

incorporates an innovative concept of heated hose in which the copper resistance is homogenously spread around the hose. This allows accurate and uniform control of the application temperature of the products.
