Clearly Cooler – Global Refrigeration solutions

Understanding the application characteristics, operating load and ambient influence of individual applications plays a major role in matching the selection to meet the performance requirements of the end user.

Working conditions change - your requirements don't

At Danfoss we understand the importance of focusing on the right components for the right application.

Consider: A cold room in the hot, dry climate of Arizona, places dramatically different demands on a compressor than a milk cooling tank in cool, damp Finland. Similarly the demands on an air drier compressor are different to a beverage dispenser - even in the same location.

With this in mind, Danfoss has developed a whole new line of refrigeration scroll compressors to complement our reciprocating and variable capacity compressors, controls, and heat exchangers.

Performance is critical - whatever and wherever the application is. To make sure you get the best possible solution, we start by asking the big questions.

At Danfoss' refrigeration labs, engineers conduct long-term, in-depth studies on a variety of refrigeration units, closely scrutinising parameters such as capacity and heat load profiles. They also examine the impact of ambient conditions on these parameters.

Perhaps most importantly, this research has taught us the value of a fully comprehensive product range. Surprising though it may seem, a scroll compressor isn't always the best solution for every application. For certain applications in some climates, a reciprocating compressor is the best and most energy-efficient option.

The brand new line of refrigeration scroll compressors complements our existing range of reciprocating and variable capacity compressors, controls and heat exchangers and selection of products can be tailored to the demands of ' your specific refrigeration application.

• Higher efficiency and lower energy consumption: A high efficiency motor and innovative refrigeration scroll wrap design reduces energy costs.
• More reliable: Fewer parts, unique manufacturing system and patented overload protection system reduces downtime.
• Silent: Compliant scroll and check valve design means less cost for low noise applications.

As food costs and energy prices continue to rise the cold chain is more important than ever. Modern consumers demand that the food they buy is cool, fresh and of consistently high quality. Shop owners expect reliable, economical and efficient refrigeration solutions. In today's business environment choosing the right supplier of efficient and reliable compressor solutions is more important than ever.

The NTZ, MPZ and VTZ compressor ranges from Danfoss have been designed specifically to cater for low and medium temperature commercial refrigeration and cooling applications.

NTZ - The Hassle-free choice for low temperatures

Dedicated to low temperature refrigeration and freezing applications, the NTZ range of hermetic reciprocating compressors is among the very best compressors available today.

A hassle-free economical choice, the NTZ is a stable workhorse, engineered and optimised for an extended evaporating temperature range from -10°C to -45°C. Its features guarantee top class performance and high efficiency at low evaporating temperatures.

• Wide evaporating range improves pulldown capabilities
• Integrated safety and robust design for many years of reliable operation
• Easy installation, as no injection cooling is required.

NTZ: dedicated to low temperature (-10°C to -45°C) refrigeration and storage.

MPZ - The compact solution for modern systems

The MPZ is the most advanced line of refrigeration compressors we have ever developed. Drawing on our vast experience at the forefront of compressor technology, the MPZ range has been designed to deliver an unmatched energy efficiency ratio, combined with space saving design, enhanced functionalities, low noise and extreme reliability.


MPZ: especially for factory assembled medium temperature (+10°C to -30°C) refrigeration systems and subassemblies.

The five models in the MPZ range cover cooling needs at evaporating temperatures from +10°C to -30°C and have each been tested thousands of hours under the toughest conditions.

• Standard foot mounting
• Oval shape for easy integration in compact systems
• Copper brazed connections guarantee 100% tight systems

VTZ - Truly adaptive cooling technology

Refrigeration compressors are usually selected based on their performance with maximum expected system loads. But what happens when systems spend up to 85% of their time well below maximum load?


VTZ is the intelligent, variable speed solution for industrial and multi-evaporator commercial refrigeration

Avoid oversized and short cycling systems by choosing a compressor that automatically adapts to the current load. By combining an efficient VTZ compressor with a CD Compressor Drive, we have created an innovative and intelligent compressor package that utilizes variable speed technology to ensure superior efficiency across the entire operating range. The VTZ is especially suited for applications such as industrial cooling processes, refrigerated food processing, compressed air dryers, or in multi evaporator refrigeration systems at petrol stations.

• Integrated new functionalities: Oil return management, Overload limitation, Anti short cycle protection, Discharge gas temperature monitoring (Accessory), Compressor rack controller: 1 variable speed + 2 fixed speed compressors.
• High COP across operating range
• Optimal load / capacity adaptation; a truly adaptive cooling technology
• Plug and play solution
