Intelligent Temperature Control PTC Heater

The CRX7 wall-mounted Intelligent Temperature Control PTC Heater is Chenrui Electric’s flagship multi-scene bathroom heater built for all-year household comfort. Its minimalist 80mm ultra-slim wall-mounted body blends seamlessly with all bathroom decor without occupying floor space. The PTC heating module delivers stable, flameless warmth, while the front circular digital control knob acts as the central operation hub of this Intelligent Heater, showing real-time temperature and adjustable timing from 5 to 95 minutes.

A rotatable bottom air outlet lets users redirect airflow for full-room uniform heating or cooling. A hidden pull-out towel rack tucks away to preserve sleek wall aesthetics, and extends to hold towels and small garments. Matched with the built-in UV-C cold cathode lamp, this PTC Heater achieves a 99.99% sterilization rate to eliminate mold, bacteria and mites on damp textiles.

Intelligent variable frequency technology automatically adjusts power output to cut energy waste, and the low-noise AC motor keeps running noise ≤60dB for undisturbed daily use. Five independent working modes—heating, cooling, drying, disinfection and mixed mode—adapt to every season. Dual power options (1500W/2200W) and universal 110V/220V voltage fit global household power standards, with lightweight 5.5kg construction for quick wall installation.

Features

• 5 multi-scene working modes: Heating, cooling ventilation, towel drying, UV sterilization and mixed composite mode for 365-day use

• Retractable hidden towel rack: Pull out to hang towels and personal clothes for simultaneous drying and disinfection; retract to maintain tidy wall layout

• UV-C cold cathode sterilization lamp: 265nm short-wave UV delivers 99.99% germ removal rate, suppresses mildew growth in humid bathrooms without chemical residues

• 360° rotatable air outlet: Freely adjust airflow angle to eliminate uneven hot/cold spots across the whole space

• Circular digital control knob: Real-time temperature digital readout, intuitive operation, 5–95 minutes stepless timer with auto-shutdown function

• Safe PTC ceramic heating core: Flameless heating with built-in overheat protection, far safer than traditional resistance wire heaters in humid environments

Specifications & Technical Advantages

Core Technical Advantages

1. Humid-environment safety optimization PTC flameless heating pairs with auto power-off overheat protection circuits to prevent short circuits and fire hazards from bathroom water vapor splashes. The UV cold cathode lamp produces zero ozone overflow, avoiding irritating fumes that harm respiratory health.

2. Remarkable long-term energy efficiency The variable frequency intelligent temperature control structure of the bathroom heater avoids continuous full-power operation. Compared with fixed-power traditional bathroom heaters, it reduces monthly power consumption by over 30% under identical usage frequency.

3. All-in-one multi-functional integration One slim unit integrates heating, cooling, drying and sterilization, eliminating separate purchases of towel warmers, ventilation fans and disinfection devices. It cuts household equipment procurement and installation costs significantly.

4. Low-loss silent operation Optimized balanced AC fan motor reduces vibration noise during operation. Internal noise reduction cotton and silenced air ducts cap overall noise under 60dB, suitable for night bathing and rest without disturbance.

5. Wide global voltage adaptation Built-in auto voltage identification circuit supports stable switching between 110V and 220V power without extra transformers, perfectly matching cross-border retail and overseas household demand.

Application Fields

1. Household Private Bathrooms The primary usage scene of the Intelligent Temperature Control PTC Heater. It fits small, medium and large wet-dry separated bathrooms in apartments, villas and self-built homes, covering winter heating, summer ventilation and daily towel hygiene maintenance.

2. Indoor Cloakrooms & Closed Balcony Drying Zones Install in home cloakrooms and enclosed balconies. Drying and UV modes speed up drying of underwear, bathrobes and swimsuits, resolving slow drying and mildew issues during rainy seasons.

3. Homestays & Hotel Guest Bathrooms Low failure rates and simple operation cut hotel daily maintenance costs. The slim minimalist body elevates bathroom premium aesthetics, while sterilization functions boost guest hygiene experience.

4. Beauty Salons & Private Spa Changing Rooms Mount in salon washing and changing spaces to deliver constant temperature heating for customers. Regular drying and disinfection of beauty towels prevent cross bacterial contamination.

5. Household Pet Washing Areas Maintain steady warm temperatures to stop pets from catching cold after baths. UV disinfection sanitizes pet towels and cleaning supplies to lower cross-infection risks between pets and owners.

Certification & Quality Assurance

Every CRX7 series Intelligent Temperature Control PTC Heater undergoes strict multi-stage factory quality inspections and holds full global market access certifications: CE electrical safety, FCC electromagnetic compatibility, RoHS eco-friendly material certification, PTC heating core safety test reports and UV sterilization efficiency certificates, fully complying with EU, North American, Southeast Asian and other mainstream regional electrical safety standards.

For strict quality control, each unit completes a 48-hour continuous aging test, humid environment simulation test, temperature control accuracy calibration and noise detection before packaging. All structural components adopt high-temperature flame-retardant ABS plastic and rust-proof metal air ducts. Internal circuit boards are coated with waterproof insulating glue to withstand long-term high-humidity bathroom environments.
