Quick selection guide

From 300 to 120,000 m³/h depending on the model, the Klimor range covers small compact units through to large modular air handling units. Helvair helps translate the building requirement into a technically coherent product family.

  • Modular standard: EVO-S
  • Restricted plant space: EVO-T or EVO-T Compact
  • Healthcare and clean rooms: EVO-H
  • Swimming pools and high humidity: EVO-P
  • Large volumes: EVO-R (X/O) or EVO-R (X/O) HPM
  • Residential and light commercial: KCX+, KCO+ or BLAST

Criteria reviewed before selection

Building use, airflow, available pressure, filtration level, energy recovery, integration constraints, acoustics, maintenance and compatibility with building management systems.

  • Commercial scope: identify the appropriate direction
  • Technical scope: prepare an actionable basis
  • Project scope: coordinate constraints with the manufacturer
  • Client scope: explain the selected solution clearly

Selection and technical support

Helvair can prequalify the project, use Klimor Air Designer and turn the selection into a clear proposal.

  • Requirements prequalification
  • Direction towards the appropriate EVO configuration
  • Coordination with Klimor documentation
  • Support through to the commercial proposal

Documented performance

Performance, compliance and certifications are checked for the range and configuration actually selected, without generalising them across the entire catalogue.

  • Confirmed airflow range and available pressure
  • Documented functions and filtration level
  • Communication protocols verified for the selected controls
  • Certifications associated with the relevant product
