ROC HX Curved Sauna Heater (External Control)

The HX has a curved stainless front that softens the look of a small sauna while keeping the stone chamber open for fast steam. With a separate control unit it covers rooms from 3 to 13 cubic metres. Casing: curved brushed stainless steel.

4 models cover sauna rooms from 3 to 13 m³: HX-45B (4.5 kW) for 3–6 m³, HX-60B (6.0 kW) for 5–9 m³, HX-80B (8.0 kW) for 8–12 m³ and HX-90B (9.0 kW) for 9–13 m³. Choose the model whose published room volume range contains your room; if the room sits at the top of a range, step up one size.

All ROC heaters run on 220–240 V single-phase or 380–415 V three-phase supply and are CE marked as standard; UL certification for North America can be arranged on request, with the cost quoted per project. The HX external-control heater is an ROC own-brand product and can be supplied under your brand through our OEM and ODM service. See the full ROC HX Heaters range. Typical use: design-led home saunas and boutique hotel rooms.

Frequently Asked Questions

Which ROC HX external-control model do I need for my sauna room?

Match your room volume in cubic metres to the published range: HX-45B (4.5 kW) for 3–6 m³, HX-60B (6.0 kW) for 5–9 m³, HX-80B (8.0 kW) for 8–12 m³ and HX-90B (9.0 kW) for 9–13 m³. If the room sits between two ranges, choose the larger model or send us the room size and we will size it for you.

No. It is wired for a separate ROC control unit such as the basic, digital, YP-T or AT86 controller, chosen to match the heater power. The control panel is mounted outside the sauna room.

Can the ROC HX external-control heater be supplied under our own brand, and is it UL certified?

Yes. It is an ROC own-brand product built for OEM and ODM supply, with your badge, colour and packaging. CE marking is standard; UL certification for North America can be arranged on request and the cost is quoted per project.
