Chromalox Keeps Railway Commuters Safe and Warm

chromalox air duct heaters The Challenge 

An OEM customer in railway car HVAC systems required both overhead heaters with open coil and tubular elements, as well as custom duct heaters to provide safe, reliable and comfortable heat on passenger railway cars. 

The Solution 

Based on drawings supplied by the customer, the Chromalox team created the initial samples for review in a very short time-frame despite the complex nature of the units. Chromalox designed and manufactured the required overhead heater with an open coil element in a sheet metal chassis and included thermostatic, over-temperature fail-safe controls to shut off the equipment should it become over-heated. Chromalox also designed and manufactured the complex and detailed mini-duct heaters to meet the customer's specifications. 

Both heaters were manufactured in accordance with the shock and vibration criteria of municipal rapid transit systems. 

The Benefits

Implemented key manufacturing changes to improve process without increasing costs 

Quick turn-around from design to sample to manufacture of finished product 

Safe, reliable, efficient heat supplied to commuters of railway transit
