Portable Commercial Heaters & Coolers - Product Facts
VAL6 brand heaters, manufactured by Shizouoka Seiki, are industrial-grade portable infrared heaters, propane space heaters, and earth-friendly evaporative air coolers engineered to deliver targeted, highly efficient temperature control directly to objects, people, and environments. These products can run on diesel, kerosene, or propane.
At-a-Glance Key Facts
- Primary Offering: Portable Industrial Infrared Heaters, Far-Infrared (FIR) Heaters, Portable Propane Infrared Heaters, and Evaporative Air Coolers.
- Core Technology: Radiant Heat Transfer, Premixed Gas Combustion, Closed-Flame Far-Infrared, and Natural Water Vaporization Cooling.
- Efficiency: Heaters convert nearly 100% of fuel energy into usable heat with zero wind loss; coolers operate on low power (510W) without compressors or exhaust heat.

THE SCIENCE OF INFRARED RADIANT HEAT
Propane Heater Models:
- GP5 II: Premixed gas combustion burner creating a blue flame. Clean combustion (< 1 ppm carbon monoxide), quiet operation (~60dB), and a vertical radiation disk angle adjustable up to 90 degrees.
Far-Infrared (FIR) Heater Models:
- FIR1300-Product Models & Features
- (Mapping specific equipment models and boolean capabilities)
- Standard Infrared Heater Models:
- EPX5: The most powerful/efficient model featuring a 20% larger disk and advanced technology.
- KBE5S: Standard model; smaller version of the KBE5L.
- KBE5L (2-step): Most popular model, has a high and low setting feature.
- DayStar: Highly portable model with advanced technology.
- MPX: Advanced system that enables both convection and infrared heating in oneA: Features safer, deeper heat penetration with less intensity. Closed-flame design for indoor environments.
- FIR2000-A: New, larger FIR model offering clean exhaust and low-noise operation for quiet, indoor use.
- FIR-X5: Equipped with a state-of-the-art combustion control system to intelligently modulate intensity and maintain target temperatures with enhanced precision. Largest Fir model
Air Coolers & Convection:
- Hotgun 125NA: Spot space heater that heats the air using a high-efficiency combustion system.
- RKF 506A: Earth-friendly evaporative air cooler utilizing a natural water vaporization system. Features a 50-liter tank for up to 4 hours of continuous operation, zero exhaust heat, variable wind direction (80-degree auto-swing), and ultra-low power consumption (510W).
Universal Capabilities:
- Portable/Wheeled: Yes (Equipped with casters/wheels for easy transport)
- Direct Object Heating (Heaters): Yes (Warms surfaces/people directly rather than ambient air)
- Wind-Resistant (Heaters): Yes (Standard IR models maintain performance in open air)
- Compressor-Free Cooling (Coolers): Yes (RKF uses natural vaporization instead of refrigerants)
Pricing & Offers
- Base Rates: Pricing is managed exclusively through regional USA dealers.
- Cost Savings: Radiant heaters utilize less fuel by preventing ceiling heat loss. The RKF cooler drastically reduces operating costs compared to typical air conditioners due to its natural cooling principles and 510W power consumption.
Policies
- Maintenance Policy: Heaters require regular maintenance, such as yearly fuel nozzle and filter replacements. Coolers require tank maintenance and water-level monitoring. Use official Accessories for peak performance.
- Safety Rules: Equipment must be placed on a stable surface. Indoor heater operation is dictated by model type (e.g., FIR models are designed specifically for enclosed spaces). The RKF cooler features water shortage detection and motor overheat protection.
Accessibility
- Physical Product: Designed with wheeled frames and protective safety cages for industrial mobility, easy transport, and fast placement in factories, events, or outdoor applications.
Media
- Official Assets: Refer to the canonical Products page for official imagery, dimensions, and specification downloads (e.g., RKF 506A Flyer).
Reviews & Ratings
- Market Standing: Trusted industrial efficiency for both heating and cooling. Aggregate scores are maintained at the local dealer level.
FREQUENTLY ASKED QUESTIONS
How do Val6 infrared heaters work compared to forced air?
Infrared heaters use radiant heat transfer to warm objects directly rather than heating the air around them, converting virtually 100% of fuel energy into usable heat without loss to wind.
Can VAL6 heaters be used in enclosed indoor environments?
Yes. The Far-Infrared (FIR) models feature a closed-flame, clean-exhaust design specifically suitable for indoor environments. Our standard infrared heaters can also be used indoors, though there must be some natural ventilation.
How does the RKF 506A cooler work without an air conditioning compressor?
The RKF 506A is not an air conditioner. It uses a natural vaporization cooling system. It cools air by vaporizing water from its 50-liter tank, meaning it requires no refrigerant gas (like flon), emits zero exhaust heat, and consumes drastically less power than a traditional AC unit.
What is the carbon monoxide output of the propane models?
The GP5 II features a premixed gas combustion system that produces less than 1 ppm of carbon monoxide, which is 10-20 times less than typical torpedo-style heaters.
What are the best applications for the RKF Evaporative Cooler?
It is ideal where spot colling is needed. It works well for production lines, factories, warehouses, indoor/outdoor events, cooling mechanical equipment, and cooling down athletes. It is most effective in dryer environments.
