The natural choiceSabroe ammonia 40 bar heat pump compressors

Types HPO and HPC

Features:

Ammonia is an ozone-friendly refrigerant Heat pump systems reduce the CO2 emission

The series covers the entire water temperature range

up to 70C.

Compared with CFC, HCFC and HFC systems you wil lgain the following advantages:

- higher efficiency (COP)

- reduced compressor size

- smaller evaporators

- smaller condensers- smaller pipe and valve dimensions

Capacity range: 100-1500 kW (one compressor)

Multiple applications

ApplicationsSabroe ammonia heat pump compressors are perfectly

suited for a large number of applications, such as:

Heat reclaim for hot/warm water production in ammonia refrigeration

plants within the food industry (abattoirs, dairies, ice creamfactories, fish processing, freeze drying, breweries, slaughter houses

etc.)

Condenser heat reclaim from refrigeration systems

Upgrading of industrial waste heat for use in industrial processes,

district heating, individual buildings, etc.

Heat pump systems based on natural heat sources such as sea

water, air and geothermal energy

Special applications such as wood seasoning, fish drying, exhaust

gas cooling in power plants, etc.

Heating in ice rinks or other sports arenas. Hot water for baths and swimming pools.

Safe use of ammonia plants

SABROE & YORK will support the use of

natural refrigerants - invest and develop

products for the purpose only!

SABROE & YORK will support the use of

R717 for many years to come - and is

therefore reluctant to see this unique

refrigerant fall into discredit due to lack of

knowledge.
