Practical Electric Heating Incubator – ToronCubator™ EH-P
The ToronCubator™ EH-P is a precision laboratory incubator designed for biochemical research, mould cultivation, and controlled-temperature biological studies. Combining a frequency-conversion refrigeration system with an advanced PMMA II operating platform, this series of laboratory incubators delivers stable, frost-free performance across a broad 5–60 °C temperature range — making it a dependable choice for demanding B2B laboratory environments.
The ToronCubator™ EH-P is a dual-purpose biochemical incubator and mould incubator engineered for laboratories that require consistent thermal control without compromise. Available in three chamber volumes — 100 L, 150 L, and 250 L — the series accommodates a wide range of sample loads and shelf configurations, making it adaptable for both small-scale research and high-throughput laboratory workflows.
Its cold-rolled steel housing with static spray-plastic finish and mirror stainless steel interior chamber offer both structural durability and easy maintenance. A large-angle, heat-preserving vacuum toughened glass window allows users to monitor samples without opening the door, reducing thermal disruption during sensitive incubation cycles. The integrated 220V power socket adds convenient in-chamber access for peripheral instruments.
Power recovery functionality protects data integrity during unexpected power interruptions — all programmed settings and active run data are retained when power is restored. This feature is particularly valuable in continuous or long-cycle incubation workflows where data loss could compromise experimental integrity.

Theory and Method
Thermoelectric Temperature Control
The ToronCubator™ EH-P operates on a dual-mode thermal control principle, combining resistive heating and compressor-driven refrigeration within a single chamber. A PMMA II microprocessor control system continuously reads the internal temperature sensor and modulates heating or cooling output to maintain the set-point. Temperature resolution is 0.1 °C, with fluctuation held to ±0.7 °C during heating and ±1.0 °C during active cooling cycles.
Frequency-Conversion Refrigeration
The refrigeration circuit uses an imported variable-frequency compressor and the R134a refrigerant — a hydrofluorocarbon with zero ozone depletion potential (ODP = 0). Frequency conversion allows the compressor to modulate its speed in response to real-time thermal load, reducing energy consumption and eliminating the temperature swings typical of fixed-speed systems. The system operates frost-free across the full temperature range, removing the need for periodic defrost cycles.
Multi-Stage Fan Circulation
A 6-stage variable-speed fan circulates conditioned air throughout the chamber to achieve uniform temperature distribution. Users can select fan speed to match the airflow sensitivity of their samples — lower speeds for delicate cultures, higher speeds for rapid temperature equilibration. Uniformity at 37 °C is rated at ±1.5 °C across the working volume.
