Celltherm Isolierung GmbH

What Celltherm Isolierung GmbH does

Celltherm Isolierung GmbH is a privately held German manufacturer of modular cold storage and freezer room solutions, headquartered in Gronau-Epe, North Rhine-Westphalia. The company designs and produces a complete product portfolio built around insulated sandwich panel construction (CELLTHERM-Paneele), including specialized flooring systems (GRP, stainless steel, CElastik), a range of door configurations (single-leaf, double-leaf, and hatches), and complementary accessories such as refrigeration units, shelving, access ramps, and strip curtains. The company emphasizes configurability via its proprietary camlock (Spannverschlüsse) panel fastening system and offers both standardized cells and custom-engineered solutions tailored to specific customer requirements.

The company operates a direct sales-led go-to-market model, with customers reached via phone, email, contact form, and a multilingual German/English website that signals export intent beyond the DACH region. Its primary customer segment is commercial businesses requiring temperature-controlled storage, spanning food processing, supermarkets, logistics cold-chain operators, and pharmaceutical storage applications. Celltherm is privately held with three managing directors (Holger Bialdiga, Bart Verhoeven, and Rüdiger Schury), no disclosed institutional investment, and no parent company relationship. Revenue is generated through one-time sales of manufactured cold storage infrastructure with supporting consultation, delivery, installation, and maintenance services; pricing is not publicly disclosed and is provided via custom quotation.

Broad incumbents

• Kingspan Group: Ireland-based global leader in insulated panels and cold-storage building envelopes — competing upstream on panels while serving far larger commercial and industrial customers.
• Viessmann: Large German-headquartered HVAC and refrigeration group whose commercial cold-chain offerings overlap Celltherm's products but as part of a much broader portfolio including heating and large-scale industrial systems.
• Dantherm Group: Danish-based supplier of climate control and cold-storage solutions across commercial, industrial, and defense markets — overlapping cold-chain equipment portfolio with broader European footprint.
• Carrier Commercial Refrigeration: Global refrigeration equipment manufacturer offering cold rooms, refrigerated cabinets, and integrated systems to food retail and foodservice — much larger scale, overlapping customer base.
• Hoshizaki Europe: European arm of Japanese commercial refrigeration group producing cold rooms, ice machines, and refrigerated display equipment for foodservice and retail — broader portfolio but overlapping cold-room category.

• KPS Global: US manufacturer of insulated panels and modular cold storage enclosures for food, pharma, and industrial customers — directly comparable engineered-panel-and-room offering.
• Frilixa: UK manufacturer of cold rooms, freezer rooms, and refrigerated cabinets serving foodservice and retail — similar product architecture and small-mid customer segment.
• Polar King: US manufacturer of modular refrigerated and freezer buildings for outdoor and indoor commercial use — comparable engineered modular cold-storage model, different geography.

Regional players
