Trefa T-750 cream aerators

Component Breakdown and Functions (common to all three aerators)

| TREFA T-750 AERATORS WITH FULL SKID (3 units)
TREFA T-750 Aerator — photograph of actual equipment | Trefa Continu Aerating Systems B.V. (Angerlo, Netherlands, est. 1966) — recognised No.1 in continuous aeration of confectionery masses. 60+ countries.
Composition of each aerator (full skid):
Aerating head (pennenkop) — patented unit
Pre-mix chamber
Feed pump (lobe pump) + frequency converter
Buffer tank with agitator and temperature-control jacket
CIP pumps and in-place cleaning manifold
PLC control cabinet + touchscreen HMI panel
AISI 316L frame, adjustable feet, full pipework IP65

All 3 aerators are identical in construction with minor differences. The difference lies in the aeration mode settings and temperature profile configured for each product type.
№ | Module | Function and Description
2 | Pre-mix chamber | Uniform air distribution in the mass prior to aeration. Minimal thermal impact on product. Reduction of frictional heating.
3 | Feed pump (lobe) | Precision feed of raw material. Frequency converter for smooth flow rate and pressure adjustment.
4 | Buffer tank with agitator | Accumulation and homogenisation of raw material. Jacket for temperature maintenance (cooling / heating).
6 | PLC+HMI control cabinet | Recipe-based control. Monitoring of specific gravity, flow rate, pressure, temperature. Alarm log.
7 | AISI 316L frame + pipework | Single welded platform. Anti-vibration adjustable feet. Protection class IP65. Complete set of pipework and fittings.
