Where heat actually comes from
In a machine panel, 70-80% of the heat is the drives, not the PLC. Sizing on cabinet volume alone underestimates the load by a wide margin; we ask for the drive schedule and compute from losses.
Practical details
- Door-contact terminal so the unit stops when the panel opens
- Washable aluminium filter with tool-free removal
- Condensate routing that does not drip onto terminals
Retrofit
Most retrofits fit the existing side-panel cut-out footprint. Send a photo of the panel and the drive nameplate; we will confirm the match before you order.
