Adapters, Airflow Switch and Automatic Speed Control

ADAPTERS: (Set of two): These extend the width of any 19-inch [482.6mm] Packaged Blower, Packaged Fan or Rack-Mounted Air Conditioner to permit mounting in a cabinet designed for 24-inch [609.6mm] units. The EIA-notched adapters are covered by a plate of mirror-finish stainless steel to match Kooltronic Standard Grilles.

These adapters are non-structural. Therefore, Packaged Blowers and Rack-Mounted Air Conditioners must be supported at the rear, due to their weight.

AIRFLOW SWITCH: Protects equipment against damage caused by loss of cooling airflow, by activating an alarm or turning off power. The switch can be mounted on any suitable surface which allows the stainless steel air vane to be placed in the critical airstream. This switch is a single-pole double throw type, with normally open and normally closed contacts.

The UL rating for the rotary snap action switch is 5 amps at 250 volts AC. A three foot [0.9m], three wire power cord is provided, allowing connection to normally open or normally closed circuits.

The choice of air vanes is determined by location and orientation in the airstream, and the normal operating air velocity at the point of installation. Refer to the chart below or consult Kooltronic Engineering for assistance.

AUTOMATIC SPEED CONTROL: The Kooltronic Fan and Blower Automatic Speed Control (Part Number KSC100) is a solid state "smart" controller packaged in a NEMA 1 type enclosure for remote mounting. The allowable input power supply range is 95 to 250 Volts, 47 to 63 Hz. It is furnished standard with an IEC 320 connector, a power supply fuse and a temperature sensor. Additional temperature sensors are optional.

The controller will operate single or multiple fans or blowers of compatible voltage and frequency up to a combined load of 6 Amps. The controller may be operated by either a control voltage signal of 0 to 10 VDC, a control current signal of 0 to 20 mA or one to three temperature sensors. With multiple temperature sensors the controller will respond to the highest sensed temperature.

The control circuit board is furnished with a terminal strip for field connecting the sensor and fan wires. A pressure type strain relief connector is furnished in the enclosure. If required by the installation or by code, this connector can be replaced with a 1/2-inch [12.7mm] trade size conduit connector.

A wide variety of control logic options can be field programmed into the controller by means of a board mounted DIP switch. These include fan idle or starting speed at 30%, 40%, 50% or 60% of supply voltage, fan on or off below the idle setting, control temperature setting of 86ºF (30ºC), 95ºF (35ºC), 104ºF (40ºC), 113ºF (45ºC), and temperature differential settings of 7ºF (4ºC) and 18ºF (10ºC). The selectable fan on/off feature is operative when the temperature(s) drop below the control temperature setting.

Consult factory for use with compatible Kooltronic fans or blowers.
