Look to Sarmaafarin for the standard ofexcellence in absorptionrefrigeration... the 16 JB
Now, more than ever, absorption comparable absorption machine, for refrigeration is a viable alternative to less energy usage and dramatically costlier methods of central station low operating costs; the automatic refrigeration.

16JB - an allaround performer
Absorption machines operate on the simple principle that under low absolute pressure, water will boil at a low temperature. The two-shell 16JB uses heat to efficiently produce refrigeration. The lower shell divided into absorber and evaporator sections, while the upper shell consists of generator and condenser sections. The evaporator section contains the refrigerant, water. A coil, thru which the building cooling system water circulates, is inserted into the evaporator to establish a heat exchange.
The refrigerant gains heat from the cooling system water, and because of low pressure maintained in the evaporator. quickly reaches sa tura t ion tempera ture and vaporizes, cooling the system water. The remainder of the cycle deals with reclaiming this refrigerant.
The affinity of lithium bormide for water causes the refrigerant vapor to be absorbed by the strong solution in the absorber section. The diluted (weak) solution is pumped into the generator, where steam or hot water is used to drive the water out of the solution as a vapor. The vapor passes into the condenser and changes back to liqid, which returns to the evaporator to be reused. Meanwhile, the strong solution left in the generator flows back to the absorber. This cycle is continuous as long as the machine is in operation.

Low operating costs
The 16JB has the lowest full-load steam rate in the industry, ensuring lower operating costs than any other comparable absorption machine!
Part Load energy savings
Energy savings can be significant if the machine is able to operate at l o w e r c o n d e n s e r w a t e r temperatures. In actual operation, design conditions of load and wet-bulb temperature do not frequently occur. Therefore, during much of the operating season, this conservation of energy is possible. 16JB chillers o p e r a t e t r o u b l e f r e e w i t h uncontrolled as low as 45 F. Thus, further savings are realized with 16JB machines thru elimination of a cooling tower bypass system, including an expensive bypass valve, piping, installation and subsequent maintenance.

- easier servicing,too!
Double sumps cutpump service time
A U-baffle in the lower shell forms two sumps in the shell, allowing storage of refrigerant or solution in one sump while the other side is being serviced. The U-baffles in both the upper and lower shells serve as a natural insulating barrier between sections. Fluids being stored need not be drained or transferred to drums, a factor that greatly reduces services time and expense.

Your 16JB has features that substantiallylower maintenance costs
U-bend generator tubes reducecostly tube bundle replacement
Hermetic pump/motor units offer freedom from maintenance, and the ultimate in simplicity and pumping re l i ab i l i t y. Hermet i c des ign eliminates the need for a separate, complicated, and possibly leakprone seal water system and auxiliary city water piping, while providing leaktightness and longer machine life. These pumps have conically
shaped bear ings which are lubricated by the fluid being pumped. The solution and refrigerant pumps are hermetically sealed; require no packing glands, machined thrust bearings, magnetic strainers, or monthly servicing. They are fully field
serviceable, and inspection is recommended at six-year intervals.
Another special feature of 16JB absorption liquid chillers is the use of U-bend generator tubes for maintenance-free operation, greatly reducing the likehood of expensive and time-consuming tube bundle replacement.
Each cupro-nickel tube is expanded in the tube sheet and tube support sheets to eliminate tube wear. The U-bend configuration allows the entire tube bundle to expand or contract as a unit when subjected to rapid temperature changes. The tube bundle floats and adjust freely as a unit, decreasing tube wear due to thermal stresses and reducing tube bundle failures.
Lithium chromate inhibitor:added corresion protectionyou can check in the field
Lithium chromate inhibitor added to the lithium bromide solution in 16JB absorption chillers provides in 16JB absorption chillers provides an extra margin of protection against corrosive damage to internal machine surfaces. It assures easier maintenance at lower costs, and dependable operation.
Lithium chromate is not only an effective corrosion inhibitor, but is also practical to measure and maintain, using the Solution Analysis Test Kit. This portable kit contains the components needed for quick and practical evaluation of inhibitor concen t ra t i on and so lu t i on chemistry - right in the field. The easy-to-use colorimeter shows immediate results ... no more delays or waiting for laboratory analysis ... now solution chemistry can be evaluated at the jobsite, and on-thespot adjustments made, if needed.

The dilution cycle begins when START-STOP switch is pressed to "stop". Holding relay (1K12) is energized and Controlsthe Cycle-Guard valve opens. When the refrigerant drops Control sequenceto a predetermined level, (SW4) opens; (1K11) and The following is for general guidance only. For (1K12) are de-energized and the machine shuts down.specific application, detailed wiring diagrams are
available from field office.Assume: there is power to the control circuit; all the
pump switches and capacity control switch are on; Cycle-Guard switch (1S4) is at "Auto"; all liquid-level switches are in normal position for running.
Press and release momentary RESET switch (1S2); holding relay (1K4), is energized and (1K4) contacts close. Press START-STOP switch (1S3) to "Start" position; holding relay (1K10) is energized and (1K10) contacts close. Control circuit is now complete, solution and refrigerant pump contactors are energized and the capacity control valve actuator starts to open the valve. Machine is now in normal operation.
The refrigerant high level switches (SW1 SW2 SW3) and thermo switches (TSW2, TSW1) control the Cycle-Guard valve, and thus prevent overconcentration.
