Tube CrystallisationTube Crystallisation► JACKET TUBE FOR TUBE CRYSTALLISATION –

Thermax has designed unique crystallisation prevention logic which is as explained below -explained below

• LiBr solution crystallises at a particular temperature and concentration. The variation of concentration of LiBr with respect to temperature of the solution is plotted in the form of a graph. The graph also shows the crystallisation line of LiBr at various temperatures and concentrations.

• Crystallisation of LiBr solution in vapour absorption machines can be prevented by preventing the LiBr from operating at any point close to the crystallisation line.

• Thus, in Thermax’s crystallisation free machines, it is ensured that LiBr operates always at a safe distance from the crystallisation line. The concentration of the strong solution of LiBr is measured continuously and accuratelystrong solution of LiBr is measured continuously and accurately.

Incorporating the most advanced & unique logic the concentration is alwayskept at a safe distance above the crystallisation point.

Inherent FeaturesInherent Features► SERIES FLOW DESIGN –

Thermax uses more reliable advanced series flow design for heat exchangers. Thermax has designed the High Temperature Generator very efficiently to lower the LiBr volume. This ensures lower energythe High Temperature Generator very efficiently to lower the LiBr volume. This ensures lower energy consumption at start up. LiBr temperature is around 155 � C and LiBr concentration is only 61%. This reduces the corrosion effect of LiBr & enhances life of the chiller.

► PART LOAD PERFORMANCE –Thermax chillers are designed at ARI 560 / JIS standards as applicable & run satisfactorily at even 10% load.

► ABSORBENT & REFRIGERANT PUMPS –Normally the pump manufacturers recommend NPSH for pumps as 0.5 m. They have Isolation valves helps to carry out maintenance without disturbing vacuum inside the chillerhelps to carry out maintenance without disturbing vacuum inside the chiller.

► REMOTE MONITORING –Thermax chillers are compatible with MODBUS protocol to transfer all the data available on the control panel display. The system can be made compatible with LONWORKS, PROFIBUS, SCADA or local BMS networks.

Inherent FeaturesInherent Features► ELIMINATORS IN EVAPORATOR -

Thermax uses unique design of eliminators / baffles which has low pressure drop on account of better spacing between tube bank & eliminator. This ensures a smooth path for the vapour (without any water Carry over) from evaporator to absorber.

► AUTO-PURGE SYSTEM –Thermax chillers are designed with robust system to collect all the non-condensable gases generated in the process. Offer OPTIONAL Automatic Purge to Drain System.

► CONDENSER WATER INLET TEMPERATURE –Thermax chillers can run at much lower condensing water inlet temperatures (as low as 15 �C). This is possible on account of its innovative crystallization control logic.

► NOZZLE SPRAYING IN ABSORBER –Thermax chillers have gravity feed design spray where the PLC logic completely controls crystallization to ensure proper penetration at all times.
