Sludge/Water

Varmevaxlare-VSV

Heat exchanger sludge/water from Lackeby Products combine innovative thinking and 40 years’ experience in this sector. This unit has been developed to meet special requirements for the heating or cooling of sludge. The unique patented design provides a compact heat exchanger with minimal maintenance needs.

Function

Lackeby Products produces heat exchangers sludge/water based on a modular principle with circular sludge channels, which means the design can be adapted to each plant’s unique conditions. The channels provide a large throughput area that keeps pressure loss low and minimises the risk of clogging. Each level of sludge channels is surrounded by a rectangular water circuit, in which water for heating/cooling flows in the opposite direction to the sludge.

The unique patented open turning chamber contributes to a compact design that is simple to install. Inspection, disassembly and maintenance are made easy because the turning chambers are mounted on a common flange. The turning chambers provide even higher heat transfer by equalising the sludge’s temperature profile. Based on a modular principle and patented turning chambers, the compact design delivers low running costs. This makes heat exchangers from Lackeby Products a good investment.

Design

The heat exchanger sludge/water is a compact design with circular sludge channels based on a modular principle and patented turning chamber.As standard, the unit is made in stainless steel (1.4436) with cover plates and supports in stainless steel (1.4301).
