INTRODUCTION

A refrigerant-oil-mixture is collected in the BDP and is dispensed from the low pressure side to the high pressure side of the compressor by means of hotgas. Any remaining liquid refrigerant is evaporating in a heat exchanger (WITT DWR) before being returned to the compressor.

Economical:

Expensive compressor oil is recycled and returned to the system instead of being wasted by manual drainage and disposal, which is costly in terms of labour, environmental health and safety considerations. Frequent automatic oil draining will keep the surface of heat exchangers free of oil and as such increase heat transfer and overall system efficiency

Easy handling:

Our standardised solution is an enhancement of the well established BDP, bringing a housing that can be opened and a higher design pressure of 40 bars, which makes it suitable for a broader range of applications. Moreover, several control options can be realised.
