MONTEC

Digital 4-way installer’s aid for demanding applications in refrigeration and air-conditioning technology

For heat pumps using R290 and refrigeration systems using CO₂ up to 160 bar.

The demands placed on refrigeration and air-conditioning technology are increasing: greater efficiency, greater safety, higher pressure – in the truest sense of the word. MONTEC supports service engineers where modern systems are setting new standards.

Tried-and-tested MONTEC functionality, even under demanding conditions up to 160 bar.

Changes in refrigeration and air-conditioning technology

Two trends are transforming the industry and creating new challenges

The refrigeration and air-conditioning sector is currently undergoing a fundamental transformation, which is characterised primarily by two key technological trends. Firstly, heat pumps using the natural refrigerant R290 (propane) are becoming increasingly important. This development brings with it significantly higher energy efficiency; however, it also places new demands on safety during servicing, as propane is classified as a flammable refrigerant and therefore requires special precautions when handling it and when working in potentially explosive atmospheres.

On the other hand, CO₂ (R744) is becoming increasingly established as the standard refrigerant in refrigeration and air-conditioning technology, particularly in supermarkets, industry and the commercial sector. CO₂ is considered particularly climate-friendly; however, due to its extremely high operating pressure of up to around 160 bar, it places high demands on technology, materials and measurement technology. Precise pressure monitoring, together with robust and safe system components, are crucial for reliable operation in this context.

Our solution

Modern refrigeration and air-conditioning technology is developing in two directions – and both place very different demands on service technology. Rather than offering a compromise solution, MONTEC provides two units designed specifically for this purpose.

Safety and precision for R290 applications

MONTEC Ex

The use of natural refrigerants such as R290 places significantly higher demands on servicing. MONTEC EX was developed precisely for this new reality.

ATEX marking: II 3G Ex ic IIC T4 Gc
for use in potentially explosive atmospheres
additional silicone sleeve to protect against knocks and drops
Refrigerants A1, A2 and A3 (e.g. propane R290)
App for controlling devices and accessories, software updates and measurement reports

Whether it’s installation, maintenance or commissioning: MONTEC EX supports technicians where it really counts – right at the installation site.

MONTEC 160

CO₂ systems are becoming increasingly prevalent in commercial and industrial refrigeration, bringing with them entirely new physical requirements. MONTEC CO₂ is specifically designed to meet these requirements.

CO₂ variant suitable for pressures up to 160 bar
Special Bluetooth pressure sensor available for pressures up to 160 bar
Integrated, robust vacuum sensor
Refrigerants A1, A2 and A3 (non-Ex)
App for controlling units and accessories, software updates and measurement logs

Whether in supermarkets, industry or commercial settings: the MONTEC 160 is built for continuous use in complex system set-ups.
