Technical description and application scope
Klimexs BT 350 is a wall-mounted enclosure air conditioner for compact control cabinets and low-to-medium heat loads, rated at 420 W DIN 3168 L35/L35. The current manufacturer page states 0…+65 °C operation, IP54 internal-circuit and IP34 external-circuit protection. The current manufacturer table lists 260 W at L35/L65, 1.2 A operating current, 6 A fuse, 189 W L35/L35 power input, 290 m³/h evaporator and 465 m³/h condenser maximum airflow, R134a refrigerant, 63 dBA sound level, 35 °C thermostat setting and EER 2.22. The current web table and the official engineering drawing show slightly different envelope dimensions; use the latest drawing revision for cut-out and installation. Panel cut-out, condensate handling, airflow openings and service clearances must be verified against the current manufacturer drawing. Application selection should consider enclosure heat load, ambient temperature, supply, mounting orientation and required protection level together.
