===Cooling system=== | |||
The E04 diffusion pump uses an 850Watt heater. The typical surface temperature will reach upwards of 200c (maximum 250c for pump body, max 400c for pump base). | |||
The pump technical data specifies the maximum water pressure should be 5bar/72.5psi. Minimum water supply temperature should be 10c, and maximum return temperature should be 35c. (presuming return in this case means "water coming back out of the pump cooling jacket") | |||
The minimum flow-rate should 75l/h^-1. | |||
This suggests that the E04 will need a radiator capable of dispersing 2.2Kw of heat (7512BTU). (NEEDS CHECKING) | |||
As the baffle and valve assembly as also have cooling-loops, some additional capacity should be factored in. No numbers exist for these parts however. As they are indirectly heated however and part of reflux prevention, they perhaps should have a secondary cooling loop or auxiliary radiator between them. | |||
