Efficient point of use cooling

  • Easy installation: Alfa Laval PoU is built as a plug-and-play module for any installation.
  • Hygienic design: Designed to eliminate risk of contamination. No internal welds, and fully drainable on the product side with no dead legs.
  • Quick response: When switching from 'stand-by mode' to 'cooling mode', cold water is available within seconds.
  • Minimized waste of water for injection & purified water due to the low hold-up volume and quick heat exchanger response
  • Minimum maintenance: The Pharma PoU is virtually maintenance free with no internal gaskets.

Alfa Laval PoU meets the stringent hygienic standard imposed by both control authorities and industry. With a unique design that gives high shear force and turbulence, this minimizes risk of bio-film build-up and ensures an efficient heat transfer. All product wetted parts in the Alfa Laval PoU are electropolished and the tubes as seamless. For quick and easy installation, the Alfa Laval PoU is supplied as a complete insulated module with a pitot tube arrangement and either manual or automatic valves. Installed in a water system, the Alfa Laval PoU module can be regarded as a sub-loop of the main loop.

Standard sizes

The Alfa Laval PoU is available in four standard sizes with a heat transfer area ranging from 0.3 m² to 1.0 m² , allowing a flow rate up to 1000 or 1500 l/h.

Hoe het werkt

.

The Pharma-line Point of Use heat exchanger in pharmaceutical industry is made up of three tubes positioned concentrically within each other. The product flows in the middle channel meeting the service media in the inner and outer channel to get full countercurrent flow and thereby efficient heat transfer.

Installed as a complete point-of-use cooler the heat exchanger is kept sanitized all the time. In stand-by mode, part of the hot WFI is taken via the pitot tube for a continuous flow through the heat exchanger. Hot WFI(Water for injection) is possible to take out through the user point. When cold WFI(Water for injection) is needed, the cooling mode is turned on, which closes the recirculation valve and opens the cooling water valve. Cold WFI is available within seconds and there is no need for flushing or draining of the system before drawing WFI or PW.

Tankreinigingsapparatuur

Het gebruik van het juiste tankreinigingsapparaat kan de stilstandtijd aanzienlijk verminderen, alsmede het verbruik van middelen zoals water, reinigingsmiddelen en energie. Onze apparaten zijn ook ontworpen om de fabrieksveiligheid te verhogen door de toegang tot krappe ruimtes voor handmatige tankreiniging onmogelijk te maken.
