Model H12NA0E
n Thermal Cycle and Airflow
The internal and external air flow circulation is shown as the figure. Through separated mechanism design, internal and external air flow will not be mixed since the waste heat can be dissipated from the cabinet to the ambient. Internal temperature sensor is placed at return air stream to provide reliable temperature measurement and safety of operation.
n Installation and wiring
Please design and install the product according to the installation holes drawings below.

| XXXX | Nominal heat dissipation capacity in watts (4 digits, e.g., 0500 = 500 W, 1000 = 1000 W) | 1500 |
| V | Input voltage option: 48 = 48 V DC (standard), 72 = 72 V DC, 110 = 110 V DC (available on request) | 48 |
Example order code: DHE‑1500‑48 – a 1500 W DC heat exchanger with 48 V DC input.
Other capacities (e.g., 300 W, 800 W, 2500 W) and non‑standard voltages (e.g., 24 V, 36 V) are available on request – please consult our sales team.
| Order Code | Cooling Capacity | Input Voltage | Recommended Cabinet Volume (approx.) | Typical Application |
