Control the
Atmosphere.
An integrated HVAC/R group. We run the 4REF wholesale network, distribute professional brands, represent EV Sun's healthy light across Europe, and develop our own products.
One HVAC/R value chain.
The name Kenro joins two Japanese words: kenrō (堅牢), meaning solid and durable, and kū (空), the fifth element — the air that binds the others. We are building a group that covers a building's entire air system.
We work across the full HVAC/R range: the technician's tools, wholesale distribution, and our own R&D. For an investor that means diversified revenue and a position across the whole chain.
Distribution
4REF wholesale and brand distribution across Poland and the CEE region. It already generates cash today.
R&D
Green HVAC/R technology and our own product R&D: know-how we own and energy-efficient hardware.
Production
The Kenro own brand — professional HVAC/R tools (the nitrogen / pressure-test line) and R&D products.
Foundation
Education and industry development — the professional relationships our sales depend on.
Our HVAC/R wholesale network. It funds the rest of the group.
1,000+ products from respected brands, a warehouse built for installers, full B2B service, and free advice from specialists who know the trade.
One network for installers and their customers.
Humido is Kenro's own digital platform connecting installers with their customers. It turns one-off jobs into ongoing relationships, and every new installer makes it more useful to the next.
humido.eu →The brands we represent.
European representation of EV Sun, plus distribution of professional HVAC/R brands across Poland and the CEE region.
Professional instruments for HVAC/R service — digital manifolds, wireless probes, vacuum gauges and meters built for the field.
Service hardware for installers — vacuum pumps, recovery machines, condensate pumps and mini-split installation tooling.
Measurement and monitoring — refrigerant scales, leak detectors, vacuum gauges, thermometers and temperature data loggers.
Refrigeration service chemistry — leak sealants, dyes, lubricants and cleaners. Consumables, so customers reorder.
Our own R&D projects.
Beyond distribution and the platform, the group develops its own products and concepts — from the Kenro own-brand tool line to early-stage R&D such as the OilSight™ concept. EV Sun's technology is patented by its manufacturer; we are its European representative.
Positioned across the whole value chain.
F-gas phase-down
The shift away from R-410A toward R-454B and R-32 drives demand for new equipment, tools and refrigerants right across the market.
The clean-air mandate
Post-pandemic indoor air quality is turning healthy light from an option into a requirement — directly into EV Sun's market.
Energy efficiency
Regulation and cost are pushing the market toward low-energy technology — exactly what our R&D targets, and where margins are highest.
Full-chain presence
Kenro earns from the technician's tool, the wholesale order and its own IP alike. Few competitors sit across all three.
