PURPOSE-
KRC remote condensers are standard OEM products of Kirby. They are intended to provide for
the condensation of fluorocarbon refrigerant for typical commercial sized refrigeration
applications, and are suitable for use in indoor or outdoor environments. They are not intended
for environments that may have harmful, corrosive or flammable atmospheres. ‘Marine’
environments are considered corrosive; please consult Kirby before installing in this
environment.
Standard Design Conditions
KRCxxx-xPH condensers are designed to operate with a maximum operating pressure of
3650kPag, with a maximum KTD of 20K, and a minimum of 5K (please refer to the relevant
technical data literature for more specific recommendations). Special circuiting may be needed
to achieve specific conditions outside of these limits- please refer to your Kirby representative.
Motors must NOT be subject to air-over-motor temperatures greater than allowed by the fan
manufacturer(s). Please refer to the relevant technical literature.
APPROVED REFRIGERANTS-
R404A/R448A/R449A/R134a/R513A/R450A and R410A are approved for use in all
KRCxxx-xPH models.
For more details, please refer to the relevant technical literature.
MAXIMUM WORKING PRESSURE-
KRCxxx-xPH models have a maximum working pressure of 3650kPag.
KRCxxx-xxH condensers cannot use Ammonia (NH3, R717), Carbon dioxide (R744), or
hydrocarbons, as refrigerant.
For special design requirements such as non standard conditions and/or fluid coolers (Glycol,
oil, etc), please inquire with your local representatives and/or Kirby local branches
