Read articleHigh pressure
Impingement mixing at high pressure with a self-cleaning head and no solvent flushing.
Overview
The Ecológica AP series brings together machines for mixing polyurethane at high pressure. The components mix by impingement inside the head, which cleans itself mechanically at the end of each shot — no solvents.
It is the reference technology for high-output, repetitive cycles such as refrigerator cabinet insulation and mould injection. Configuration starts from the application: output, number of heads, temperature conditioning and integration with mould carriers.
Mechanical cleaning on every shot, with no solvent and no flushing waste.
Several configurations to meet each customer’s technical and economic requirements.
Metering designed for repetitive cycles with controlled ratio and shot time.
Can work with Sulpol mould carriers and automation in refrigeration and moulding projects.

Next step
To recommend a configuration we need to know the product, the polyurethane system, the mix ratio (by weight or by volume), the target output and the operating mode.

Metering and mixing
Portable metering
Portable metering with Sulpol engineering: up to 15 or 30 kg/min, 1:1 mix ratio by volume.
Low pressure
Dynamic mixing for flexible, integral-skin, rigid and semi-rigid foams.
Elastomers
Low pressure for PU elastomers: up to 150 kg/min, up to 150 °C, dynamic head and up to 4 additional components.
Application engineering
We will look at your application, target output and metering requirements to assess the right equipment configuration.
