III. INSTALLATION
A.
PLACEMENT AND MOUNTING
The radiator is designed for locations that allow adequate airflow to and from the
radiator. For engine mounted radiators, there should be no obstructions in the airstream
other than the engine. If ductwork is used on the radiator’s air discharge, its cross-
sectional area should be equal to or larger than the core area. The ductwork should be
straight or include large radius turns with no sharp corners. Consult Rocore for
recommendations regarding airflow restrictions caused by ducts, louvers, or other
obstructions.
Take precautions to allow a free flow of air to and from the radiator to prevent
recirculation of the heated discharge air from the radiator back into its intake system.
The unit should be no closer than one unit width away from any obstruction, wall or
another radiator. Keep a minimum clearance around the radiator for maintenance and
repair.
The installation should consider the potentially negative effects of prevailing winds on a
radiator’s performance. Do not face a vertical radiator’s discharge airstream into a
prevailing wind.
Remote radiators usually are not sized to accommodate engine room or any other air
rise, or external static restrictions to airflow, unless specified in the application design
data.
Standard remote radiators should be bolted to a level, solid foundation or structure.
Spring type isolators are not recommended for applications that require vibration
isolation between the radiator and the foundation or structure. Spring type isolators can
allow or induce vibration or movement to the radiator, which will void the warranty.
Instead, rubber-pad type vibration isolators are recommended.
Engine-mounted radiators must not be allowed to float freely from the engine. If
isolators are to be used, the radiator must be rigidly mounted to the engine, with the
engine/radiator combination mounted together on isolators.
CAUTION! Rocore standard radiators are designed for a maximum of 250 degrees
Fahrenheit and 20 psi(g) operation. Exceeding these limitations will void the warranty.
1. GENERAL
All Rocore radiator assembly drawings include mounting dimensions.
2. MODEL ‘N’ TYPE RADIATORS (FAN ON ENGINE)
This type of radiator should be mounted to the engine skid with the mounting
holes provided at the bottom of each side member. The customer should provide
bracing from near the top of the radiator side member down to the engine skid
(See Fig. 2A).
