Advantages of the CRL evo at a glance
New Sizes:
- 3+3 additional sizes from 1,300 m³/h to 4,900 m³/h
- Available for both indoor and outdoor installation in horizontal design
- Improved modularity with only one separation point for the larger indoor units
Latest high-quality components:
- Pocket filters with long service life
- Newest fan generation with highly efficient IE5 motors
- Outdoor and exhaust air dampers with spring-return motors
Optimal Air Conditioning:
- Powerful, infinitely variable, and integrable electric heating coils
- Optimal heating or cooling of the air in combination with the Clima-Split system in combination with
a sorption rotor
The heart of the system – the rotary heat exchanger:
- specially angled wave profile offers maximum efficiency
- Two different sealing systems:
- Conventional brush seal or highly efficient labyrinth seal with a tightness rate of 98% in accordance with VDI 3803 T5 and biologically inert design - Three rotation types – suitable for every application:
- Condensation heat exchanger for transferring sensible heat in dry areas such as warehouses
- Enthalpy heat exchanger – ideal for comfort ventilation in offices or hotels, with improved humidity in winter
- Sorption heat exchanger for very high moisture transfer in applications with high humidity requirements
Application example with increased hygiene requirements
- All surfaces easily accessible and cleanable in accordance with VDI 6022
- Thermal insulation T2/TB2 and best tightness class L1
- Optionally available with spring return drive for dampers that close automatically in the event of a power failure and prevent wind and buoyancy circulation
- Supply air filter up to ePM1 85% (F9) available in the unit
Application example: Educational institutions
- Space-saving installation and easy installation thanks to compact design and demountable versions
- CO₂-controlled volume flow regulation for optimum air quality with maximum energy savings
- Use of bag filters for long service life and high particle separation efficiency
Application example: hotel
- Healthy indoor air thanks to demand-based operation with CO₂ or air quality sensor
- Highly efficient dehumidification of outside air in summer mode and humidification of outside air in winter mode using an enthalpy rotor or sorption rotor
- Optimum air conditioning in combination with WOLF Clima-Split

Difficult site conditions for engineers and installers? WOLF offers just the right answer: the Easy Lifting System. It makes transport onto or into a building much easier, and the installation of these functional units becomes quicker and more accurate. It’s so simple that even our largest components, such as thermal wheel or plate heat exchangers, can be easily brought into any building or positioned on the roof.
The Easy Lifting system also makes a great contribution to the hygiene of WOLF AHU appliances. The intelligent connection and transportation technology virtually eliminates the risk of leakages in heat exchangers or appliance modules caused by installation errors.Our unique synergy of software and products is unrivalled in the industry.
It makes our appliance configurations highly adaptable, our production methods efficient
and also keeps our delivery times remarkably short.
