PROPANE (R290) WATER CHILLERS
AND HEAT PUMPS
Sustainability, energy efficiency, redundancy, plant safety and life-cycle
costs are the criteria taken into account for the development of our future-
proof water chillers and heat pumps. Wherever possible, we already
rely on the use of natural refrigerants that are proven to be efficient, safe,
environmentally friendly and future-proof for the respective application.
Water chillers and heat pumps are designed in such a way that the
refrigerant charge is low and high plant availability is ensured. An exten-
sive safety concept ensures safe operation of the systems.
The use of natural refrigerants, especially hydrocarbons such as R290,
is particularly suitable in air-cooled water chillers and heat pumps
for outdoor installation. Legal restrictions on the filling quantity and
EX protection requirements to be observed in individual cases can be
implemented well here. The refrigerant neither has an ozone depletion Advantages of hydrocarbons

Fulfilling future bans and market regulations today.
Direct and indirect emissions of water chillers and heat pumps
The emissions of liquid chillers and heat pumps are composed of direct and
indirect emissions. Direct emissions are caused by leaks and the escape of
refrigerant into the atmosphere. Choosing the natural refrigerant R290 with
R290
ENVIRONMENTALLY
FRIENDLY
a very low GWP = 3 (global warming potential), leads to avoiding notable
direct emissions. The commonly used refrigerants R410A (GWP = 2090) and
R134a (GWP = 1430) in comparison are damaging to the climate.
Increasing the energy efficiency of the systems influences the indirect emis-
sions (current consumption). The efficiency-optimized generous design of the
main components ensures high energy efficiency ratios (EER). As a standard,
electronic injectors are used. A generously dimensioned condenser surface
ensures a low condensation temperature.

Quotation of the German Federal Environment Agency
on the use of HFC refrigerants:
“For new systems, the Federal Environment Agency does not
consider these refrigerants [HFKWs] as trendsetting, as long
-term safe alternatives are available with halogen-free, natural
refrigerants such asCO₂, NH₃ or hydrocarbons.”

F-GAS REGULATION*
The use of fluorinated greenhouse gases is regulated by the European Parliament in the F-gas Regula-
tion (EU) No. 517/2014 and Regulation 2006/40/EG. The F-gas Regulation, amended in 2014, came
into force on 1st January 2015, significantly tightening the previously F-gas Regulation No. 842/2006
from 2007.
The objective of the new F-gas Regulation is to contribute to a reduction in the amount of F-gases emit-
ted in the EU in “tonnes of CO2 equivalents” of 70 % by the year 2030 compared to the level in 1990.
The quantities of HFCs available on the market will be reduced in stages.

Reducing the quantity of HFCs available on the market and introducing additional HFC refrigerant
taxes from 2015 onwards will inevitably lead to supply bottlenecks, increasing refrigerant prices, push-

Statement by the German Federal Environment Agency:
“Due to the quota system introduced in the EU, a significant in-
crease in the price of R404A and other refrigerants with a high
GWP is to be expected.”
“Whether this will lead to a shortage of refrigerants within the next
ten years, remains to be seen.”

Following entry into force of the new regulation, as from 01.01.2020 new systems may only be filled with
refrigerants with a GWP lower than 2500. Applications with cooling temperatures below -50 °C are not
affected. A further tightening of the regulations for new plant will comes into force on 01.01.2022. From
then on, multipurpose centralised refrigeration systems for commercial use with a capacity of more than

INTELLIGENT MACHINE CONTROL
As control systems we use the freely programmable controllers. They are ideally suited for incorporating our many
years of experience in refrigeration and air-conditioning technology into our specially developed control algo-
rithms. In the design of our control programs, the main focus of our in-house programming department is on user-
friendliness, high availability as well as the efficiency of the systems..
Visualisation – Everything at a glance
The schematic representation of the
system shows all important process
data at a glance.
Detailed information about each ac-
tuator can be found on its information
screen.
Malfunctions or irregularities are high-
lighted in colour directly on the respec-
tive system component and in full text
in the alarm list. The intuitive display
concept ensures easy user-machine
interaction.

Control system
The heart of the machine control system is the control algorithm which ensures efficient and trouble-free opera-
tion of the system. Thanks to “condition monitoring”, the constant monitoring and analysis of all components and
process data, faults are detected as soon as they arise. As a result, for example, maintenance can be planned in
advance. However, should there be any irregularities or malfunctions, the machine responds autonomously and
provides the maximum possible power during emergency operation, despite any impairment.
Integration and communication
Thanks to the implementation of various bus interfaces, the systems can be easily integrated into existing processes.
These interfaces include among others Industrial Ethernet, Profibus-DP, Modbus-RTU, Modbus-TCP/IP and CANopen.
Data logger / Data plotter
Recording and analysis of a wide range of process data is becoming increasingly important. For this purpose,
our controller provides the user with a freely configurable data logger. The relevant data can be easily selected
via process visualisation. The controller automatically saves the data as a *.csv file on an SD memory card.
When required, the data can also be sent to a server. To be able to conveniently analyse the sometimes large
amounts of data, the controller additionally includes a data plotter which converts the recorded data into mean-
ingful line graphs. It is also possible to save the graphs as *.jpg, *.png or *.csv files.
PROPANE WATER C HILLERS 9SKADEC REMOTE MAINTENANCE
The powerful programmable logic controllers (PLC) of the series PFC with the in-house SKADEC chiller
software are IP capable as standard and provided with a web server for process and data visualisation.
Thanks to the use of HTML5, the visualisation can be operated and displayed with all popular end
devices such as smartphones, tablets and PCs using HTML5-capable web browsers (Microsoft Edge,
Google Chrome, Mozilla Firefox, Apple Safari, etc.).
To access the machine control outside the intranet, a secured connection can be used via a VPN router,
permitting remote monitoring, remote maintenance, troubleshooting, alarm reporting as well as long-term
process analysis and process optimisation. The router is conform to ISO27002, IEC62443-2-4, NIST Cy-
ber Security Framework 1.0, BSI TR-02102-1 & TR-02102-2 (German Federal Office for IT safety).
Communication
The VPN router can be connected to the Internet via Ethernet (Standard RJ-45), WLAN or the mobile

12 R 290 WATER C HILLERS WITH FREE COOLING AND SPEC IAL SOLUTIONSFree cooling
All water chillers are optionally available with a free-cooling register arranged hydraulically in series.
Free cooling is used when there is a year-round demand for cooling in combination with higher system
temperatures. The use of sliding free cooling already permits in the transitional period mixed operation
of mechanical and free cooling, thereby greatly increasing the energy efficiency of the system.
Advantages
• Cooling without cold compression
• Short amortisation period of the additional investment
• Great reduction in CO2 emissions
• BAFA bonus funding possible (+30% above basic funding)
Air conditioning application
Propane water chillers in combination with a water or cooling brine
circuit are ideally suited for air conditioning of industrial or office build-
ings. High requirements for energy efficiency and noise protection
must be taken into account.
Process cooling
Operational safety and redundancy are the focus of product develop-
ment of propane chillers for process cooling. The application of free
cooling is used for appropriate system temperatures.
Cold storage and supermarkets
Propane chillers can be specially tailored for use in supermarkets and
for the storage of refrigerated goods such as fruit and vegetables.
Optimisation of energy costs while reducing dehumidification of re-
frigerated goods is becoming increasingly attractive to operators.
