Product catalog summary
Overview
Winterwarm presents the ACM, a modular air curtain system designed to create an invisible barrier between indoor and outdoor environments. This system is aimed at maintaining a comfortable indoor climate while being energy efficient and easy to install and maintain.
Key Characteristics
  • Creates a comfortable indoor environment.
  • High air volume with optional EC-fan for enhanced performance.
  • Energy-saving design.
  • Simple installation and maintenance.
Sustainability and Comfort
The ACM air curtain helps maintain a stable indoor temperature by preventing drafts and external odors from entering. It is effective in both winter and summer, providing a barrier against cold air and retaining warm air inside.
Modular Design
The ACM consists of 50 cm modules, allowing it to fit various door sizes. It draws warm air from the ceiling and directs it to the ground, reducing heat loss and maintaining comfort without drafts.
Energy Efficiency
Research indicates that air curtains can reduce energy losses by 60-80%. The ACM features a Gurney Flap for improved efficiency and a powerful fan (AC or EC) to ensure effective separation of indoor and outdoor air.
Applications
  • Shops
  • Hotels and restaurants
  • Supermarkets
  • Shopping malls
  • Loading bays
Technical Specifications
The ACM series is available in various configurations, with specifications including:
  • Maximum suspension height: 4.5 meters (standard) and 5.5 meters (EC series).
  • Air volume ranges from 1,900 to 22,500 m³/h depending on the number of modules.
  • Sound levels range from 34 to 74 dB(A).
  • Electrical consumption varies with module count, requiring additional supply for wider installations.
Installation and Control
The ACM can be installed horizontally and controlled via a door contact relay or a 5-step/stepless controller. It is less effective when installed vertically.
Company Background
