We are pleased to quote the following, Prepiped and Prewired Model DC 10000S DIRECT
CONTACT WATER HEATER with Integral 4,000 Gallon Tank and Pumping System, to be
installed by the purchaser. This system is designed on the basis of the information supplied to
us by your plant to handle the following approximate quantities and temperatures and
produce the stated results.

CUSTOMER REQUIREMENTS:

Hot Water (Maximum) ----------------------- 12,000 GPH (200 GPM @ 140 Deg. F.)
Hot Water (Average) -------------------------- 7,200 GPH (120 GPM @ 180 Deg. F.)
Cold Water (Minimum) -------------------------------------------------------- 40 Deg. F.
Cold Water (Average) ---------------------------------------------------------- 60 Deg. F.
Natural Gas Pressure (1,000 BTU/FT ) ------------------ 5 PSIG @ 10,000 FT /HR.

HEATER CAPACITY:
Direct Contact Water Heater (Patent No. 4574775) is rated at 10,000,000 BTU/HR and is
capable of heating 200 GPM from 40 to 140 Deg. F. at sea level to 1,000 foot elevation. Water
can be heated to a 180 Deg. F. temperature at a reduced water flow.

ESTIMATED ANNUAL VALUE OF HEAT LOAD REDUCTION:
Based upon heating 7,200 GPH of water from 60 to 140 Deg. F., 40 hours per week for 52
weeks per year, and natural gas at a cost of $6.00 per 1,000 CU FT., the annual cost reduction
would be $25,060.00 when compared to a conventional gas-fired heater or boiler system
operating at 70% system efficiency.

LUDELL EXTENDED WARRANTEE:
Ludell warrants its water heaters against defects in material and workmanship, under normal
use and service for a period of five (5) years after shipment for the fabricated stainless steel
shell and one (1) year for all other components. Ludell's obligation is limited to repair or
replacement f.o.b. Ludell's plant. Please note that customer supplied water chemistry may
adversely affect the equipment materials of construction. If the water supply is aggressive,
acidic or high in chlorides a higher-grade stainless steel alloy must be utilized. Contact Ludell
for a quote revision if your supply water chemistry is of poor quality.
