Sutton Stromart Limited products

Radiators, more correctly called Air Cooled Heat Exchangers (ACHE), are large pieces of equipment compared to other types of heat exchangers and require free space around them for the cooling airflow. Tube bundles (the core) configurations are positioned horizontally (with vertical airflow as shown), or can be arranged vertically (with horizontal airflow). Placement can be in front of the engine with an engine driven fan, or remotely with an electric motor driven fan. Typically the ACHE is mounted near the engine to minimize piping cost and pressure drop. Alternatively, it can be installed beyond a bulkhead, on a slab in front of a structure, or on a rooftop.

Sutton individual finned tubes are most commonly spirally wound aluminium strips around copper piping and have a high contact resistance.

High heat transfer copper round tubes with aluminum louvered plate fins. Tubes are mechanically expanded into self spacing fin collars for maximum heat transfer. Type L copper headers are used for inlet and outlet with MPT steel connections that can be fitted with flanges for field connections. 3/8” FPT steel vent and drain connections are provided for each circuit.

Flat fin oval tube radiators are what are found on a typical OEM factory engine mounted radiator. They provide efficient cooling and are well suited to being used in a square configuration with a single engine or electric motor driven fan. The core is produced from copper and brass with oval welded or lockseam tubes. Fin surfaces can have louvers for more cooling efficiency.

Serpentine Fin construction radiators are what we most commonly see in transportation and can also be found on smaller generator engines. These can be lower cost because of the light gauge aluminum or copper materials. They are also the most prone to leaks and have the shortest life of the construction types available.

Direct drive fan motors are the preferred way to drive fans as this eliminates belts, bearings and other moving parts outside the motor. This design is free of maintenance apart from greasing at regular service internals and visual inspections for fouling.
