Transmission Oil Coolers

The Thermex GB range are the perfect Oil Coolers for small marine transmissions and are ideal fuel and engine oil coolers for lower duty marine engines. Their extruded aluminium body and polyamide headers make them a durable and cost effetive alternative to the traditional brass tube marine transmission coolers. Independent tests have proven that the Thermex GB series coolers can provide up to 60% greater thermal performance than the traditional brass tube equivalents under the same conditions.
