Clean / pure steam

Many of the products shown are alsoavailable for clean or pure steamapplications in the biotechnology,pharmaceutical, food and drink industries.

Flash steam recovery

48 Flash vessels are used to convert pressurised condensate into useful flash steam - used here on the first stage of an air heater battery.

Condensate recovery

49 Combined pump traps and pressure power pumps for condensate removal and return (no electrics).

50 Electric pump sets used where condensate can freely drain into a receiver.

Engineered Systems

A complete, compact steam heat exchange solution for process, heating, and domestic hot water requirements.

The environment

Steam has always been environmentally friendly - modern, highly efficient centralised boiler plant ensures emissions are minimised and the steam itself condenses to pure, unpolluted water. Spirax Sarco remain at the forefront of improving the efficiency of the entire steam and condensate loop and are the only company with this total capability.
