suitable for very cold climates?
Certainly. The LO-CAT® reaction is exothermic. The blower for the oxidizer air adds about 50-70 degree C to the ambient air temperature, so the air inlet to the oxidizer is seldom a problem. The primary temperature issue occurs when the plant is shut down for an extended period. In such cases, tank insulation and pipe tracing should be used to limit heat loss from the LO-CAT® system.
