29	RESISTANCE WELDING	IGNITRON TUBE - SIZE E 48,600 BTU/HR = 4 TON UNIT
30	RESISTANCE WELDING	RECTIFIER(IF REQUIRED) - AMPS X 3.413=BTU/HR	EX. 300 AMPS X 3.413 = 1023.9 BTU/HR = 1/4 TON
25	RESISTANCE WELDING	WELDING TIPS- 3,000 BTU/HR PER TIP (CHILLED WATER PEFERABLY)	10 TIPS X 3,000 = 30,000 BTU/HR = 2.5 TON
31	PLATING BATHS	HEAT REMOVAL (BTU/HR)= DC AMPS X DC VOLTS X 2.9	200AMPS(DC) X 50 VOLTS (DC) X 2.9 = 29,000 BTU/HR = 2.5 TON
3	INJECTION MOLDING	40#/HR NYLON = 1 TON	120LBS PER HOUR = 3 TON CHILLER
1	INJECTION MOLDING	30#/HR H.D. POLYETHYLENE = 1 TON	90LBS PER HOUR = 3 TON CHILLER
2	INJECTION MOLDING	35#/HR L.D. POLYETHYLENE/POLYPROPYLENE = 1 TON	140LBS PER HOUR = 4 TON CHILLER
4	INJECTION MOLDING	50#/HR POLYSTYRENE OR ABS = 1 TON	150LBS PER HOUR = 3 TON CHILLER
5	INJECTION MOLDING	65#/HR PVC OR POLYCARBONATE = 1 TON	195LBS PER HOUR = 3 TON CHILLER
6	INJECTION MOLDING	70#/HR P.E.T. = 1 TON	280LBS PER HOUR = 4 TON CHILLER
34	INDUCTION UNIT	1 Kilowatt = 3,420 BTU'S	10 Kilo watt unit = 34,200 BTU'S (Half of units energy produces heat) / 2 = 17,100 BTU'S = 1.5 HP Chiller
14	HYDRAULIC COOLING	1 TON/HP	5 H.P. UNIT = 5 TON UNIT
17	FEED THROAT	400 TON MACHINE OR ABOVE = 1 TON 400 TON AND LESS = 1/2 TON	500 TON MACHINE = 1 TON UNIT
21	EXTRUSION EQUIPMENT	BARREL OR SCREW COOLING = 1 TON PER INCH OF SCREW DIAMTER	6 INCH DIAMETER SCREW = 6 TON CHILLER
20	EXTRUSION EQUIPMENT	FEED THROAT 3" SCREW OR LESS = 1 TON	1" SCREW = 1 TON
19	EXTRUSION EQUIPMENT	FEED THROAT 3" SCREW OR ABOVE = 2 TON	5" SCREW = 2 TONS
18	EXTRUSION EQUIPMENT	GEAR BOX COOLING - 1 TON PER 100 HP	300 H.P. = 3 TON CHILLER
9	EXTRUSION	80#/HR PVC = 1 TON	160LBS PER HOUR = 2 TON CHILLER
8	EXTRUSION	75#/HR POLYSTYRENE = 1 TON	150LBS PER HOUR = 2 TON CHILLER
7	EXTRUSION	50#/HR POLYETHYLENE OR POLYPROPLYLENE = 1 TON	250LBS PER HOUR = 5 TON CHILLER
32	DIE CASTING-ZINC	HEAT REMOVAL (BTU/HR) = M X 95 BTU/LB M= THROUGHPUT RATE (LBS/HR) POUR AT 800 DEGREES FAHRENHEIT REMOVE AT 300 DEGREES FAHRENHEIT
33	DIE CASTING-ALUMINUM	HEAT REMOVAL (BTU/HR) = M X 325 BTU/LB M = THROUGHPUT RATE (LBS/HR) POUR AT 1200 DEGREES FAHRENHEIT REMOVE AT 600 DEGREES FAHRENHEIT
22	CONTINOUS STEEL QUENCHES	HEAT REMOVAL (BTU/HR) = M X 0.13 X (T1 - T2) M= THROUGH PUT RATE (LBS/HR) T1= STEEL TEMPERATURE INTO QUENCH (DEGREES FAHRENHEIT) T2= STEEL TEMPERATURE OUT OF QUENCH (DEGREES FAHRENHEIT)	6,000LBS/HR X 0.13 X (1200 - 900 DEGREES F) = 234,000 BTU/HR = 19.5 TON CHILLER (USE 20 TON)
10	BLOW MOLDING	40#/HR POLYOLEFINS = 1 TON	80LBS PER HOUR = 2 TON CHILLER
35	BATCH STEEL QUENCHES	HEAT REMOVAL (BTU/HR) = M X 0.13 X (T1 - T2) / t M= THROUGH PUT RATE (LBS/HR) T1= STEEL TEMPERATURE INTO QUENCH (DEGREES FAHRENHEIT) T2= STEEL TEMPERATURE OUT OF QUENCH (DEGREES FAHRENHEIT) t = QUENCH TIME IN HOURS
11	AIR COMPRESSOR	(NO AFTER COOLER) = 0.16 TON/HP	10 H.P. UNIT = 10 X 0.16 = 1.6 TON UNIT
12	AIR COMPRESSOR	(WITH AFTER COOLER) = 0.2 TON /HP	10 H.P. UNIT = 10 X 0.2 = 2 TON UNIT
16	WATER PUMP IN CIRCUIT	0.2 TON/HP	10 H.P. UNIT = 10 X 0.2 = 2 TON UNIT
15	HOT RUNNER MOLD	1 TON/10.5 KW	31.5KW = 3 TON
