concentrate heater

Concentrate Heater

22 June 2018

At over 6 meters long and less than 1 meter wide, the double stacking provides a small foot print to save valuable factory floor space. Manufactured in house from T304, T316 and exotic Duplex SAF2205 stainless steel, this steam heated, insulated, twin barrel, concentrate heater is destined for the New Zealand dairy industry. To gain complete code compliance with AS1210 the finished unit was pressure tested to 633bar (9,300 psi) as its operating pressure will be at 375bar (5,500 psi).

The general concept is similar to a shell and tube heat exchanger but fabricated to strict hygiene requirements with all mechanical parameters confirmed by Finite Element Analysis (FEA) and conformation to the latest seismic criteria. The removable end caps allow access to the shell's internal surface and both the internal and external surfaces of the multiple heat exchange tubes.

Air Heater 2019

Air Heater

31 May 2018

A bespoke vertical airflow Air Heater fitted with code compliant steam and condensate heat exchangers and 120kW of boost electric resistance heating to lift low temperature ambient air to over 200°C in a single pass. This all stainless steel unit was designed and manufactured in-house to meet the strict hygiene requirements and exported to Australia for use in the Dairy Industry.

shell and tube heat exchangers

Shell & Tube Heat Exchangers

5 May 2016
