What Our Clients Say

Frequently Asked Questions

Answers to common questions from facility managers and HVAC engineers evaluating air treatment systems.

What air handling unit size do I need for my facility?

AHU sizing depends on your required airflow rate (m3/h or CFM), heating/cooling loads, humidity targets, and filtration class. Our application engineers perform a load calculation based on your facility drawings and process requirements to recommend the optimal configuration. Typical commercial buildings require 6-10 air changes per hour; pharmaceutical cleanrooms may require 20-60 ACH.

How do I choose between desiccant and refrigerant dehumidification?

Refrigerant-based systems are cost-effective when target humidity is above 45% RH and ambient temperatures are moderate. Desiccant systems are essential when you need dew points below 10°C or when operating in cold environments where refrigerant coils would frost. Many applications benefit from a hybrid approach combining both technologies.

What certifications do your products carry?

Our AHU and dehumidification systems carry Eurovent Certified Performance, CE Marking, UL Listed, ISO 9001, ISO 14001, and AHRI Certification depending on the product line and target market. We provide full documentation with every shipment.

What is the lead time for a custom air handling unit?

Standard modular AHU configurations ship within 6-8 weeks. Fully custom units with specialized coatings, unusual dimensions, or atypical filter configurations typically require 10-14 weeks. We maintain buffer stock of common components to accelerate delivery for urgent projects.

Do you provide on-site commissioning and maintenance?

Yes. Our service network covers 85+ countries with 45 regional service centers. We offer full commissioning, preventive maintenance agreements, filter replacement programs, and 24/7 emergency support for critical-environment clients. Remote monitoring packages are available for real-time system health tracking.

How does heat recovery reduce my operating costs?

Our rotary heat exchangers recover up to 85% of thermal energy from exhaust air, reducing the heating/cooling load on fresh supply air by a measurable margin. In temperate climates with 4,000+ heating degree days, this translates to 25-40% reduction in HVAC energy costs. The payback period is typically 18-30 months depending on local energy prices and annual operating hours.
