We are pleased to quote the following, Prepiped and Prewired, (Fully Factory Package) Model
DC 5600S DIRECT CONTACT WATER HEATER with Integral 1,800 Gallon Tank and Single
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 ------------------------------------------- 6,720 GPH (112 GPM @ 140 Deg. F.)
Cold Water --------------------------------------------------------------------------- 40 Deg. F.
Natural Gas Pressure (1,000 BTU/ FT ) ----------------------- 2 PSIG @ 5,600 FT /HR.

NOTE: All figures are in U. S. Units of Measurement.

HEATER CAPACITY:
Direct Contact Water Heater (Patent No. 4574775) is rated at 5,600,000 BTU/HR and is capable
of heating 112 GPM from 40 to 140 Deg. F. at sea level to 1,000 foot elevation. Water can be
heated to 180 Deg. F. at a reduced flow.

ESTIMATED ANNUAL VALUE OF HEAT LOAD REDUCTION:
Based upon heating 5,580 GPH of water from 35 to 135 Deg. F., 40 hours per week for 30 weeks
per year, and natural gas at a cost of $8.00 per 1,000 CU FT., the annual cost reduction would be
$20,160.00 per year 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.
