All the compressors listed above are available in tandem-ready versions, which can easily be integrated into any tandem
assemblies to increase the heating capacity and, at the same time, to create modulation capability.

Today, the ZH range of Copeland Scroll™ heating compressors is the most
used technology for dedicated heat pump applications, delivering outstanding performance and reliability. Emerson Climate Technologies has
now extended its ZH range with tandem-ready versions and new singlephase models. Seven Copeland Scroll™ heating compressors with a
larger operating envelope have been released.

Energy and Climate Challenges
In 2007, the European Council decided to drastically
reduce green house gas emissions and the consumption of primary energy until 2020. In this plan, the share
of renewable energy shall reach 20% of the total energy
consumption. This will boost both government support
and end-user awareness for renewable energies creating
a market overall favourable to the growth of heat pump
technologies.
Benefits of Copeland Scroll™ Heating Compressors
Emerson Climate Technologies:
Large Investments in Scroll Compressor Design
Copeland Scroll™ compressors are used by all major
dedicated heat pump manufacturers. Emerson Climate
Technologies has invested significant resources and
carried out extensive testing to optimize the ZH range
of Copeland Scroll™ compressors for residential and
commercial heat pump applications in new buildings or
for boiler retrofit.
Production in Europe for Europe
To ensure high levels of service, Emerson Climate
Technologies continues to serve the European market
with local production of ZH range of Copeland Scroll™
heating compressors from the factories in Northern
Ireland and Belgium.
Growing Demand for Dedicated Heat Pumps
Increasing energy costs of gas or oil heating systems,
coupled with the need to meet CO2 emission targets,
resulted in the growing interest for dedicated heat
pumps. Rather than burning fossil fuels to produce heat
and consequently CO2 emissions, dedicated heat pumps
use renewable energy from the environment like air,
ground and water. They consume up to 70 % less primary
energy and therefore drastically reduce the pollution
resulting from the use of fossil fuels.

Alco Controls
Alco Controls provides a full range of controls to heat
pump manufacturers across Europe. These products
include:
• Electronic Expansion Valve (EXL/M, EX4-8)
• Superheat Controllers (EC3-X32/-X33)
• Thermo®-Expansion Valve (TX3/6)
• Filter Drier (ADK/FDB, BFK)
• Pressure Switch and Transmitter (PS3/4 and PT4)
• Fan Speed Controller (FSX, FSY and FSP)
• Sight Glass with moisture indicators (MIA)
• Smart Starters for single-phase compressors
(ESC-255/325)
• Solenoid Valves (110RB, 200RB, 240RA and 540RA)
More Heating Capacity
The Copeland Scroll™ heating compressor delivers higher
capacity at low evaporating (heat source) temperatures
thereby better responding to heating requirements than
reciprocating compressors. It also results in less supplementary heating to cover the full heating demand on the
coldest days.
High Efficiency
The Copeland Scroll™ heating compressor has a special
scroll design, which attains high efficiency in heat pump
operating conditions, especially when the heat source
temperature is low. As for all Copeland Scroll™ compressors, the run time has a positive impact on the
efficiency of ZH heating compressors.
Quiet Operation
ZH heating compressors have been designed for low
sound levels, a specific requirement for indoor heat
pumps.
Higher Water Temperature for All Applications
The ZH heating compressor has been optimized for
applications in new buildings where water temperature
demand for space heating is 50°C . The ZH heating compressor with vapour injection has been further optimized
to enable heat pumps to efficiently produce water temperature up to 65°C during cold winter time. This is a
new technology in space heating and tap water production, which permits traditional boilers to be replaced
by heat pumps in retrofit applications without changing
the radiators.
Highest Performance with
Enhanced Vapour Injection Technology
The ZH Copeland Scroll™ heating compressor with
vapour injection has an additional port to inject vapour
in the compression process. This improves the performance of the system by increasing the heating capacity
for a given compressor displacement. Additional benefits
are the reduction of the discharge temperature and the
extension of the operating envelope for the production
of high temperature water.

with Vapour Injection Technology
Durability and Reliability
The ZH heating compressor reaches the same high standards of durability and reliability as any other Copeland
Scroll™ compressor. This includes the ability to handle
relatively large amounts of liquid, which is known to
damage or break reciprocating compressors. Fewer
moving parts, robust running gear and low vibration
due to balanced compression mechanism make the ZH
range of Copeland Scroll™ compressors the most reliable solution available on the heat pump market.
