6.3 Timed Power ON/OFF Cycling of CHC Treatment
Not all customers require 24/7/365 operation of the CHC Treatment. The CHC treatment system is
designed to treat the water within the system whenever there is a load present on the system, as well
as periodically treat the water on a non-loaded system to enhance the calcium removal and control
bacteria growth.
So when a customer asks “Do we have to operate our CHC unit and Filtration units 24/7?”. And
the answer may surprise you. “Yes and No.”
Let me explain:
Evaporative Condenser Customers-
For a customer who has an Evaporative Condenser and runs their system dry for extended periods
of time throughout the winter. We can help.. These types of customers frequently use an indoor
drain down sump, and it is that sump that our CHC and Filtration systems treat. We can work with
each customer to customize a schedule to power ON and OFF the systems to maintain treatment of
their sump while minimizing the Bacteria growth. We have also suggested the use of Bleach (we
have an application formula) to increase the OFF time of the systems. These types of customers
can greatly save on energy if they use this approach.
Other Evaporative Condenser Customers do not use a drain down sump, but may also be able to
utilize this Power Cycling approach. Only customers who have a heated basin, and have insulated
and heat taped the CHC systems can use a similar approach. Other customers may not need to
utilize this approach if they currently drain their systems during the winter and leave our systems
Off anyway. If the customer stops the CHC and Filtration systems and does not have them
winterized or drained, the system may freeze and could possibly destroy gauges, pipes, strainers
and even pumps. So we are very selective about who we share this ON/OFF Power Cycling
approach with.
Cooling Tower Customers-
Most Cooling Tower customers utilize a chiller and would never qualify for the use of the above
mentioned approach to energy conservation. However, there are customers who do not use their
chillers in Winter, and move towards the use of a heat exchanger instead or only use the Cooling
Tower on the work days and not on the week ends. These type of customers could utilize this
approach and save money.
New Customers-
As we qualify each new customer, we need to keep in mind the types of towers they have as well as
their current usage through out the year. If that information is sent to CHC for quote with any
further information about the customer’s desire to be energy efficient, EcoWater CHC can look at
this information and suggest the use of energy efficient pumps (cost premium), or the use of a
Power Cycling Schedule or both. In any way, the customer should feel that EcoWater CHC offers
more than just water treatment, it offers the engineering, sales coordination and care about our
customers to make their application a success.
