Heat Exchangers Explained

What are plate heat exchangers?

A heat exchanger transfers heat from one fluid to another with the intention of either cooling or heating one of them. A plate heat exchanger is a particular type that uses metal plates to transfer heat between two liquids. Typically, a series of pressed metal plates are aligned, to provide a greater surface area. The major advantage of this system is that due to the surface area, the speed of the temperature transfer is vastly increased.

Where are heat exchangers used?

Heat exchangers are used in a lot of applications from heating and air conditioning, refrigeration, chemical processing, power generation and food production. However, our range is particularly focused on the food production industry for everything from producing juices, yoghurts, milk, sauces and more.

What we supply

Powerpoint International supply a full range of tubular and plate UHT/HTST heat exchangers. Suitable for a wide variety of products with any holding time flow rate our customers require, our UHT heat exchanger range starts from the simple Mini Bench Top @ 10 litre per hour, the Econo-Lab series @ 20 litre per hour, through to the bigger machines at up to 200 litre per hour for pilot plant or process machines which start as small as 500 litre per hour. All are available with either tubular, plates or scraped surface heat exchangers. The small range up to 100 litre per hour does not require any steam, and very compact and is contained in a mobile stainless steel cabinet.

Some of our products

Tube and Plate UHT/HTST

This is a combined machine with tubes and plates on one base, designed for easy changeover from one system to the other with the touch of a button. Simply select which system is to be used from the touch panel menu and the machine is ready to use.

There is no need to remove the plates and replace with tubes or vice versa, the divert valves will change the product and service flow through whichever system is chosen.

Individual tubes are utilized to give a wide variety of heating and cooling duties. The tubes are manufactured to our own specification and are profiled to give turbulence at the low flow rates to enable scale up to production.

No bond Gasketed plate heat exchangers to give a wide variety of heating and cooling duties. The plates are manufactured to our own specification and can be supplied as 1 complete plate pack or individual units for easy maintenance.

Mini Plate UHT/HTST
