OUR HISTORY
From a Specialist Tool Mail-Order Company to a full-range Digital Retailer.
Founded in 2008 as Kellermann Klima GbR. Today, it is an Owner-Managed GmbH with an International Team and a Product Range of over 20.000 Items.
Five Stages in which an idea has developed into a Specialist Retailer.
2008 – 20102008
Foundation — Online Retail meets Refrigeration Technology.
André (Refrigeration Engineer) and Hendirk (E-Commerce) founded the Predecessor to today’s H+H Kältetechnik. Their initial Product Range consisted of Specialist Tools for the Industry — sold via their own Online Shop, long before this became the Norm.
2010 – 20122011
First European Brands, First Employee.
Rising Quality Expectations among Customers are leading to a targeted expansion of the Product Range to include European Manufacturers. With the arrival of the first Member of Staff, the Depth of Advice on offer is also increasing.
2013 – 20152014
11,500 Items, new ERP System, Conversion to a Limited Liability Company.
Structural Optimisation: Introduction of a new Merchandise Management System, Reorganisation as H+H Kältetechnik GmbH, Streamlined internal Processes. A Foundation for predictable growth.
2017 – 20202019
Full-Range Supplier — Ventilation, Air Conditioning, seven Languages.
With the Addition of Ventilation and Air-Conditioning Products, H+H has become a Full-Range Supplier. The relaunch of the Online Shop in seven Languages and optimised direct Deliveries mark the Company’s transition to becoming a supplier with a European focus.
2021 – 20232022
Own-Brand Products — Albatros (Bathroom Extractor Fans) & Decarbonize (R290 Heat Pumps).
Two Own-Brand Ranges specifically expand the Portfolio in areas where the Market needs sustainable solutions: quiet Ventilation and Natural Refrigerants. The range now Comprises over 20.000 Items — with a clear focus on Quality and Innovation.
