1 KES Enviro Engineering Manual INTRODUCTION The SPRING AIR SYSTEMS INC. Kitchen Enviro System (KES) has been designed and constructed specifically for a commercial kitchen exhaust. The units are simple to operate and easy to maintain. The individual components have been selected to provide trouble free, reliable operation.
2 The KES unit is installed to clean the exhaust air of grease and odor. The UL/ULC listing allows the exhaust to be discharged at low levels. In other words the exhaust ductwork may be discharged through side exterior walls below the roof level. These exceptions to the standard NFPA-96 code are possible with a combination high efficiency filtration system and a unique electrical and mechanical safety circuit.
3 Within the KES Enviro Filter Unit (KES-ISH) the exhaust air travels through three stages of particulate filters. 1.Two (2) inch (51 mm) pleated - 30% ASHRAE 52-76 filters 2.Twenty-one (21) in. (525 mm) bag - 90% ASHRAE 52-76 filters 3.Twelve (12) in. (305 mm) box - 95% DOP filters, (99% ASHRAE 52-76) Within the KES Enviro Filter Unit (KES-ISH) the exhaust air is cleaned of airborne grease, lint and dirt particulate.
4 KES ENVIRO FILTER UNIT (KES-ISH) The KES Enviro Filter unit contains the LV10 panel, pressure switches, and three stages of filters. The unit is constructed of 16 gauge steel inner shell, continuously welded and liquid tight in accordance with the NFPA-96. The outside of the unit is wrapped in 1.5” insulation and 18 gauge steel protective covering primed and painted. Channels running along the length of each side support the unit.
5 Every KESF unit is equipped with a backward Inclined; AMCA rated, Class II, exhaust fan with heavy-duty bearings, and two groove sheaves. The following options are also available: The KESF fan unit is always internally isolated. The KESF fan unit has spring mounted isolators inside the KESF fan unit and does not require any external flexible connection outside the unit. The KESF fan unit has a Class II: The Class of the fan is dependent on the total static pressure and CFM of the system.
6 minutes for a preset spray time. Both the cycle time and the length of spray are adjustable. The time setting relates to the type of cooking and appliances under the hood. See Figure 7.

7 INDOOR VERTICAL UNITS Indoor, vertical units are also available for exhaust volumes up to and including 10,000 CFM. The unit is generally located beside the hood or in a mechanical room on the floor.

10 KES-ISH ENVIRO BOX CONTROLS LV10 J-Box The main Enviro Unit interlocks from the remote panels is the LV10 J-Box located on the KES Enviro Filter Box (KES-ISH). The LV10 j-box is located on the same side of the KES-ISH as the filter access and toward the exhaust inlet end.
11 NORMAL: Exhaust airflow is normal and the unit is functioning properly. FIRE: There is a temperature in excess of 225 F in the KES-ISH inlet. The unit will shut off completely. PANEL MOUNTING HOLES LOCATED IN PANEL BACK. 5" 8.0" FILTER OVERIDE NORMAL WARNING FIRE PREFILTER CLOGGED BOX FILTER 14" CLOGGED BAG FILTER CLOGGED FILTER REMOVED PRE FILTER CLOGGED: Operation will stop. The 2” deep pre-filter located in the KES-ISH filter unit is plugged and must be replaced.
12 The remote annunciation panel RPD10 is located in the kitchen near the water wash control for annunciation of the following conditions: NORMAL: Exhaust airflow is normal and the unit is functioning properly.

14 KES SELECTION Two parameters are required to select a KES unit; the total exhaust volume, CFM (l/s) and the external static pressure, inches W.C. (kpa). To minimize the initial capital cost and future operation and maintenance costs the most important consideration is to reduce the total exhaust air volume. Spring Air Systems sales representatives have a KES Enviro selection computer program. Contact your local representative and a selection can be made in minutes.
15 The external static pressure is made up of many components. Here are a few to consider: a)Spring Air Kitchen exhaust hood - typically between 0.5 to 1.5” W.C. (0.13 to 0.33 kpa) Calculated by Spring Air. b)Exhaust inlet ductwork from the hood to the KES-ISH filter box. c)Internal Static Pressure of KES-ISH filter box - typically between 2.0 to 3.5” W.C. (0.50 to 0.88 kpa). Calculated by Spring Air. d)Exhaust ductwork from the KES-ISH filter unit to the KESF fan unit.
16 Sample Selection A hospital cafeteria is expanding the kitchen. An additional SPRING AIR SYSTEMS water wash hood model HF-B 10.4 is to be installed. The cafeteria is located on the first floor of a four-(4) story section of the hospital. The exhaust must discharge at the ground floor level into a courtyard. A SPRING AIR SYSTEMS kitchen enviro system (KES) is required. Water wash hood: CD-B 10/4 Length: 10 ft. Width: 4 ft. Exhaust volume: 3,000 CFM External Static Pressure: 1.26” W.C.
