Description

Our ACE enclosures are designed for outdoor units of heat pumps and air conditioning systems from virtually all brands. They combine effective noise reduction of 9 to 17 dB(A) with unobstructed airflow, ensuring that the desired performance is maintained. To prevent loss of efficiency, the integrated anti-recirculation panel separates intake and exhaust air. In addition, the enclosures are manufactured from galvanised steel with a self-supporting frame and a maintenance-free finish. This protects the equipment against weather conditions and debris. Access panels provide easy entry, and the enclosures can optionally be powder-coated in any RAL colour for a durable and visually integrated finish.

Applications

The wide range of ACE models ensures a suitable enclosure for almost any heat pump or air-conditioning unit. In special cases, bespoke enclosures can be produced. For optimal ventilation, maintain at least 500 mm of free space around the enclosure and avoid placing units directly against walls or obstacles.

Answers to common questions

Answers to the most common technical and practical questions.
Does Merford provide service and maintenance for ACE and DICE?

Yes. We provide inspections, preventive maintenance, and repairs to maintain the performance of ventilation, sound insulation, and safety certifications. This ensures the enclosure remains reliable throughout its entire lifespan.

How is airflow and cooling ensured?

Both series are designed with custom ventilation grilles, internal air channels, and optional filters. CFD simulations are used to determine the optimal airflow, ensuring equipment stays cool without compromising noise or safety standards.

Are the enclosures modular or customizable?

Yes, both ACE and DICE are modular. Dimensions, frames, doors, and internal compartments can be adjusted to ensure the enclosure perfectly fits technical installations or space constraints.

What is the difference between ACE and DICE enclosures?

The DICE enclosure is louvre-based and suited for variable sizes and airflow. The ACE enclosure is designed for low-frequency noise, with acoustic panels for maximum sound reduction in confined areas.
