CSL-800

Compact ventilation unit with plate heat exchanger

Flexible indoor unit. Ensures a comfortable indoor climate in spaces such as open-plan offices, meeting rooms, common and break areas, medical practices, or larger sanitary facilities.

The compact air handling unit

PROKLIMA CSL-800

Optimized for small installation spaces and high comfort: reliable and highly efficient ventilation, dehumidification, heating, and cooling.

Compact, energy-efficient, and easy-to-install ventilation units with plate heat exchanger for smaller areas with high occupancy in commercial and communal buildings. Nominal air flow rate at 150 Pa external pressure: 710 m³/h. Floor-mounted, wall-mounted, or ceiling-mounted versions allow for a high degree of flexibility in installation.

► Application area: 300 to 800 m³/h

Highlights at a glance

The compact, continuously variable ventilation unit is designed for air flow rates between 300 and 800 m³/h and offers three installation options: floor-mounted, wall-mounted, or ceiling-mounted. Thanks to ready-to-connect piping and wiring, it is plug-and-play capable and can be installed and commissioned quickly and easily.

Heat Recovery

Heat recovery via a high-performance plate heat exchanger with an efficiency of over 90%.
Optional: An enthalpy heat exchanger ensures both maximum heat recovery and optimal energy efficiency, while also enabling effective moisture management.
Standard integrated bypass for night-time ventilation during summer heat (use of free cooling).

Low Energy Consumption

Latest-generation, continuously variable, energy-efficient IE4 EC fans from leading European manufacturers — either volume flow or speed controlled. Optional: CO₂, VOC, or humidity sensors
Optional: water-based heating coils or electrically integrable, continuously adjustable pre- or reheating coils (4.3 kW)
Optional: direct expansion coil (R32) or water-based changeover coil for heating and/or cooling

Hygiene

Designed in accordance with VDI 6022 hygiene guidelines
Panel filters in accordance with ISO 16890 (supply air filter ePM1 55% with long service life and quick-release filter system). Optional: visual filter indicator and an additional filter stage for especially high hygiene requirements
Easy access for cleaning and maintenance with smooth, even surfaces and floors, including stainless steel condensate trays for drainage

Control

Plug & play thanks to complete wiring and optimally positioned sensors (e.g. CO₂ and/or VOC sensors)
High-quality, plug-in, intuitive 4.3″ BMK touch control module. One control module can be used for multiple units (CSL‑800 can also be operated without a connected BMK touch). Wired remote control including wall mounting bracket BMK‑F for easy adjustments (can be installed in the room). Time scheduling program possible
PROKLIMA WRS‑K control system with interfaces for building management technology. Remote access via a web browser for detailed settings, operating mode changes, and data logging. Compatible with PROKLIMA Smartset Portal, Link Pro, and building management systems via Modbus RTU/TCP, BACnet/IP (AMEV profile AS‑B), Ethernet, and KNX

Housing

The compact CSL‑800 ventilation unit also fits through small openings and into confined plant rooms and can be installed on the floor or mounted on the wall or ceiling
Meets L1; D1; T2; TB2; F9 and is non-combustible in accordance with DIN 4102: A1 (tested by TÜV Süd in accordance with DIN EN 1886)
Supply air connection optionally on the left or right side
Optional: 2-in-1 solution – combined outdoor and exhaust air damper with just one actuator
Optional: simple duct system connection with insulation frame, flexible connectors, and adapter insulation module (round and rectangular)
Dimensions (H × W × D), including 126 mm feet: 1,159 × 1,380 × 340 mm

Energy Monitoring

Real-time display of fan performance and recording of energy consumption over the entire lifecycle of the ventilation unit. A bar chart shows the energy consumption of the last 13 months
Real-time display of both the currently recovered and the total recovered energy over the entire lifecycle. Breakdown into total, thermal energy, and cooling energy. A bar chart compares the recovered heating and cooling energy with the additionally supplied heating and cooling energy over the past 13 months
