Auerhaan Klimaattechniek

What Auerhaan Klimaattechniek does

Auerhaan Klimaattechniek (legal entity Auerhaan BV) is a Netherlands-based distributor, assembler, and service provider of climate technology products, headquartered in Lelystad, Flevoland, and operating exclusively within the Dutch market. Founded in 1885 and part of the SALOR-groep conglomerate, the company today specializes in ventilation, air handling, heat recovery, heating, and cooling solutions for installation contractors, industrial customers, OEMs, residential construction, and utility/commercial buildings. Its core technical offering centers on IV Produkt's Envistar range of air handling units — Envistar Compact, Top, Flex, and the modular Flexomix — supplemented by integrated heat pump and DX cooling modules (ThermoCooler HP, EcoCooler) and the IV Produkt Cloud remote-monitoring service. The portfolio is completed by Helios ventilation products (box, axial, centrifugal, roof, duct, and pipe fans), Koolair air distribution components, and an own-label range of Auerhaan-branded industrial axial and centrifugal fans assembled in Lelystad.

The company's revenue model is anchored on hardware sales of these products, complemented by professional services covering consulting, commissioning, and maintenance. Sales are executed through a direct, field-led motion with dedicated phone lines and a 24-hour quotation request system targeting professional installers and advisors; the distribution footprint relies on the Lelystad headquarters, warehouse, and assembly facility for nationwide delivery. Competitive positioning is built on multi-brand aggregation under one supplier with a system guarantee covering the complete installation, made most strategically relevant by the May 2025 exclusive Netherlands representation agreement with IV Produkt. Management is led by Roy Titulaer (Algemeen directeur); the firm employs approximately 19 people and is privately held with no public ticker or external venture funding disclosed.

Scale indicators6 records

Recent moves5 records

Expansion highlights5 records

Direct peers

• Brink Climate Systems: Netherlands-based manufacturer and supplier of ventilation units, heat recovery systems and air distribution products. Comparable to Auerhaan's residential and light-commercial ventilation focus, with overlapping product categories in heat recovery and demand-controlled ventilation.
• Holland Heating International: Dutch HVAC equipment distributor and integrator serving commercial, industrial and residential markets in the Netherlands. Closest direct peer to Auerhaan given similar national distribution model, multi-brand portfolio, and installer/contractor customer base.

Regional players

• Climar: Portuguese HVAC equipment manufacturer and distributor specializing in air handling units, heat recovery and climate solutions. Similar product portfolio and business model to Auerhaan, but primarily serves the Iberian and Lusophone markets rather than competing directly in the Netherlands.

Broad incumbents

• Systemair: Swedish-listed European HVAC manufacturer with broad product range in air handling units, fans and air distribution. Comparable in product portfolio, end-market exposure and integrated heat pump offering, but operates at much greater scale and across many countries versus Auerhaan's Dutch focus.
• TROX: German global leader in ventilation and air distribution components including grilles, dampers and air handling. Comparable product overlap with Auerhaan via Koolair grilles and HVAC integration, though TROX is a direct manufacturer at international scale rather than a regional distributor.
• Helios Ventilatoren: German market leader in ventilation products with 3,000+ standard catalog items covering fans, duct and roof fans for residential, commercial and industrial use. Auerhaan represents Helios in the Dutch market; comparable in product breadth and channel model even though Helios is significantly larger.
• IV Produkt: Swedish manufacturer of energy-efficient air handling units with integrated heat pumps, founded 1969, ~€166M annual revenue and 65,000+ delivered projects. Auerhaan's exclusive Dutch representative and the source of its flagship Envistar product line, so highly comparable in technology even if larger and manufacturing-led.
• Zehnder Group: Swiss-listed European leader in indoor climate solutions including heat recovery ventilation, radiators and clean air. Overlaps with Auerhaan in heat recovery ventilation for residential and commercial buildings, with similar end-customer focus but a publicly listed, multi-country profile.
• Swegon: European provider of indoor climate solutions including air handling units, heat recovery, chillers and controls. Comparable in offering energy-efficient air handling and integrated climate solutions, but operates pan-European from Sweden/Italy with much larger scale than Auerhaan.

Others

• Koolair: Spanish/European manufacturer of air distribution components including grilles, diffusers and thermally controlled air outlets. Already a partner of Auerhaan in the Dutch market, but comparable as an adjacent component supplier in the same HVAC value chain with overlapping customer base of installers and project specifiers.
