Alfa introduces plate heat exchangers

Alfa Laval has unveiled a series of plate heat exchangers (PHEs) developed specifically for high-theta duties.

The T-Series now encompasses three new PHEs - the TL6B, T5B and TL3B - offering a liquid flow capacity of 20kg/s, 13kg/s and 4kg/s respectively.

The units are extremely compact - the TL3B is 73cm long, the T5B is 78cm and the TL6B is 1.3m - and therefore enable both installation and service space requirements to be kept to a minimum.

On all TL units the tightening bolts are located on the side to facilitate service.

The tall, narrow design of the TL6B and its efficient plate pattern make it suitable for duties with long thermal length - also known as high-theta duties.

The TL6B's ability to achieve close temperature approaches and to increase heat recovery suits it to applications requiring energy efficiency such as district-cooling interchanger, district-heating substation or cooling/heating pressure breaker applications.

The compact size and high thermal efficiency of the T5B makes it suitable for most HVAC applications, but especially for domestic hot water systems, general heating and district-heating substations.

The compact and efficient TL3B allows users to optimise domestic hot water or heating systems for energy efficiency - even when the flow is limited.

Examples include domestic hot water, district-heating substations and heat recovery from swimming pools.

Depending upon the liquids involved, plates and nozzles can be made of either stainless steel or titanium.
