- Temperature distribution: ±1.0°C uniformity at 37°C in continuous operation.
- Triplex glass door: dual outer glazing plus inner door for heat retention, with a W516 × H416 mm observation window and key.
- Refrigeration and heating: air-cooled hermetic 300 W compressor (R404A) paired with a 750 W iron-chrome wire heater.
- Defrost management: manual ON / auto OFF defrost with timer and cycle operation.
- Dual sensing: Pt100Ω controller sensor plus K-thermocouple overheat prevention.
How to Choose the Right Incubator
Refrigerated incubators differ by chamber size, achievable temperature range, and control sophistication. Match these axes to your protocol.
- Temperature range: the −10 to +50°C span enables sub-ambient work that heat-only units cannot reach.
- Control type: PID control with programmable steps supports ramped or cyclic profiles rather than single fixed setpoints.
- Voltage: select 115V or 220V to match available site power and avoid transformer add-ons.
- Footprint: Yamato lists external dimensions (W × D × H) of 710 × 645 × 1630 mm (28.0 × 25.4 × 64.2 in); packed for shipping it measures 39 × 39 × 78 in at 475 lb.

Frequently Asked Questions
What is the operating temperature range of the IN804W?
The IN804W operates from −10 to +50°C. This sub-ambient capability supports low-temperature tests and environmental conditioning that heat-only incubators cannot perform.
How large is the chamber and the overall unit?
The chamber holds 286 L. Yamato lists external dimensions (W × D × H) of 710 × 645 × 1630 mm (28.0 × 25.4 × 64.2 in); packed for shipping it measures 39 × 39 × 78 in at 475 lb.
What voltage options are available?
Two voltage configurations are offered: 115V (IN-804W-115V) and 220V (IN-804W-220V). Select the one matching your site power; both share identical specifications otherwise.
How accurate and uniform is the temperature control?
Temperature control holds ±0.3°C accuracy in continuous operation. Distribution uniformity is ±1.0°C at 37°C, managed by PID control with a Pt100Ω sensor.
What materials are used in the interior and exterior?
The interior is stainless steel. The exterior uses chrome-free electrogalvanized steel plate with a chemical-proof baked finish, and styrene foam provides insulation.
What is the difference between IN-804W-115V and IN-804W-220V?
IN-804W-115V is the 115V configuration. IN-804W-220V is the 220V configuration. Order the catalog number that matches your facility's electrical supply.
