Refrigerated Incubator Programmable 286L Overview
Yamato lists external dimensions (W × D × H) of 710 × 645 × 1630 mm (28.0 × 25.4 × 64.2 in); packed for shipping it measures 36 × 34 × 73 in at 442 lb. Refrigeration comes from a 300 W air-cooled hermetic compressor (R404A). Manufactured in Japan, the unit ships with ISO 9001:2015 and ISO 14001:2015 documentation.
Key Features
- Programmable PID control: precise setpoint management across the full -10 to +50°C range.
- High-accuracy temperature: ±0.3°C control accuracy and ±1.0°C distribution at 37°C during continuous operation.
- Forced air convection: uniform heat distribution backed by a 750 W iron-chrome wire heater.
- Dual sensing: Pt100Ω controller sensor plus a K-thermocouple for overheat prevention.
- Flexible defrost: manual ON / auto OFF defrost with timer and cycle operation.
How to Choose the Right Incubator
Selecting a refrigerated incubator means matching chamber capacity, temperature range, and site power to your testing protocol. Use these axes to confirm the IN804 fits your workflow before ordering.
- Temperature range: the -10 to +50°C span covers low-temperature and environmental tests below ambient, which non-refrigerated incubators cannot reach.
- Control type: programmable PID control supports multi-step profiles, an advantage over fixed-setpoint analog units.
- Voltage: choose 115V or 220V to match your laboratory circuit and regional power supply.
- 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 36 × 34 × 73 in at 442 lb.

Frequently Asked Questions
What is the chamber capacity and how large is the 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 36 × 34 × 73 in at 442 lb.
Is the IN804 available in both 115V and 220V?
Yes. The IN804 ships in 115V (IN-804-115V) and 220V (IN-804-220V) configurations. Select the voltage that matches your laboratory circuit and regional power supply.
What materials are used in the chamber and exterior?
The interior is stainless steel for corrosion resistance. The exterior is chrome-free electrogalvanized steel with a chemical-proof baked finish, and styrene foam provides heat insulation.
