If this rule is disregarded, the vapour can be sucked in by the vacuum pump and the pump performance can break down. • The coldest point of the glass chiller should always be at the top of the glass cooler to prevent the vapour from shooting through. • The flow of the circulating cooler should be connected to the upper cooling coil connection. • Methanol • Ethanol • Water & water mixtures (batch) (water & water mixtures) Hei-CHILL 600 Cooling capacity at 600 W > 800 J/g • Methanol • Ethanol • Water & water mixtures • High volume batches • 24/7 Hei-VOLUME Distimatic Simply smart - automatically process unlimited amounts Multiple Evaporators Only with Hei-CHILL 1200 or Hei-CHILL 600 Power levels are additive ( e.g.Hei-CHILL 1200 will perform for two Hei-CHILL 600 (2*600 W)) Hei-CHILL 250 and Hei-CHILL 350 are not recommended for multi
