BLOWDOWN TANKS

IN COMPLIANCE WITH PM60 FROM THE UK HEALTH & SAFETY EXECUTIVE

The Clayton Blowdown Tank is designed to safely handle the discharges from the automatic blowdown on the Clayton Steam Generator. Water is collected in the sump of the vessel so that it cools naturally. Any additional water entering the tank replaces this standing water, which overflows into the outlet. If required, a thermostatically controlled forced cooling system can be provided which will reduce the water temperature to around 40 O C. This system is particularly useful when several boilers are connected to the same tank.

Designed to PD5500:2000 Cat 3 (Lloyds inspected) PED compliant. Design pressure 7 barg. Design Temperature 171 Deg C. Material BS1501-151 Grade 430A
