Introduction; Warranty; Heat Reactivated Dryer Nomenclature - Ingersoll Rand EH Serie Manual De Operador

Ingersoll Rand Heat Reactivated Desiccant Dryers are designed to
adsorb moisture from compressed air. The dryers are constructed with
two towers, each containing desiccant beads, that alternate between on-
line (drying) and offline (regenerating) modes, yielding a continuous
stream of dry air at the dryer's outlet.
During normal operation, wet air passes through the on line tower and
water vapor from the air is adsorbed (collected) on the desiccant beads.
While air is being adsorbed in the on-line tower, the moisture on the
desiccant in the offline tower is removed by a process called desorption
(regeneration). In standard heat reactivated operation, after an initial
rapid depressurization, a portion of dried air from the on-line tower
The Company warrants that the equipment manufactured by it and
delivered hereunder will be free of defects in material and workmanship
for a period of twelve months from the date of placing the Equipment in
operation or eighteen months from the date of shipment from the factory,
whichever shall first occur. The Purchaser shall be obligated to promptly
report any failure to conform to this warranty, in writing to the Company
in said period, whereupon the Company shall, at its option, correct such
nonconformity, by suitable repair to such equipment or, furnish a
replacement part F.O.B. point of shipment, provided the Purchaser has
stored, installed, maintained and operated such Equipment in
accordance with good industry practices and has complied with specific
recommendations of the Company. Accessories or equipment furnished
by the Company, but manufactured by others, shall carry whatever
warranty the manufacturers have conveyed to the Company and which
can be passed on to the Purchaser. The Company shall not be liable for
any repairs, replacements, or adjustments to the Equipment or any costs
of labor performed by the Purchaser or others without Company's prior

2.0 INTRODUCTION

passes through a heater and over the desiccant bed and carries the
moisture off the bed and out the dryer's exhaust. With the dryer's Bi-
Mode feature, the dryers may also be operated in a Heatless mode,
which uses more purge air but does not require use of the heater.
The continuous, alternating process of adsorption and desorption is
controlled using a customized Programmable Logic Controller that
switches the towers in a specific timed sequence. Very dry compressed
air dew points are achieved through the continuous switching and
operation of this dryer. Ingersoll Rand offers heat reactivated dryers to
provide either -40°F or -100°F pressure dew point outlet air.
