the engineering, delivery, installation,
startup, maintenance and system integration that goes with that designation?
Are custom solutions available?
Who will complete the startup? Does
the supplier have a service network or
will they subcontract this service with
someone else? Knowledge of the equipment and system integration is critical.
Are flexible financing options available,
including rent-to-own, leasing and long-term rental agreements?
What is the supplier’s reputation in
terms of HVAC knowledge and expertise, customer service and equipment
reliability?
permits required? Are there limitations
placed on operating hours (emissions,
noise, etc.)?
Who will complete the system integration
(setup, startup, decommissioning, etc.)?
Who will maintain the temporary equipment?
What is the delivery commitment upon
receipt of notification/order?
Site Preparation
After the cooling requirements have
been identified, and the supplier and
equipment selected, it is time to prepare
the facility for quick installation of the
In Summary
Temporary-cooling solutions are
important in emergency situations where
an interruption of cooling is unforeseen.
These systems can also provide uninterrupted cooling during planned shutdowns
of HVAC equipment, keeping businesses
operational while equipment is repaired
or replaced or when cooling loads increase.
Temporary cooling is most effective, from
both a financial and an operational standpoint, when it is part of a contingency
plan that defines the cooling requirements
of a business, identifies a supplier, spec-ifies equipment and establishes a site-preparation plan.

the rigors of outdoor installation – including the harsh northeast winter – and to operate quietly in a
campus environment.

Evaluating the Proposal
Proposals for temporary-cooling
solutions should include a description of
the application, design conditions, equipment and the services to be provided by
the supplier. In addition, one should obtain
details relating to payment schedule, issues
of liability coverage and change orders.
When reviewing the proposal, it is a good
idea to be sure that the following questions
are answered:
Are temporary equipment specifications,
locations and system tie-in points (
electrical and mechanical) identified?
Is temporary power generation required?
If so, how will fuel be provided? Are
temporary-cooling system. This means
installing quick connections to the facility.
Both electrical and mechanical connections
must be considered and may include
bypass valves, breaker panels, duct connections, etc.
Some suppliers of temporary-cooling
solutions will perform facility-preparation
work as part of an emergency-prepared-ness plan. York International, for example,
offers these services as part of an agreement that is filed along with a detailed
analysis of cooling needs. In the event of
an emergency, the information will allow
YORK to respond quickly, providing critical
cooling where it is needed, while reducing
customer financial risks and downtime.
