Efficiency and total cost of ownership
The purchase price of a temperature control unit is a fraction of what it costs over its lifetime. Most of the cost is the energy it consumes every day for years.
In industrial equipment, the energy cost Throughout its useful life it easily exceeds the purchase price. The efficiency —variable speed pump, proportional regulation of cooling water, PID control with autotuning and insulation—acts on the largest item of the total cost of ownership.
The purchase price is the tip
In the industry it is common to analyze the total cost of ownership (TCO): the sum of what it costs to buy, operate and maintain equipment throughout its useful life.
In equipment that operates many hours a year, energy dominates that total: the operating cost throughout its useful life can multiply several times the purchase price. The exact figure depends on the process, hours of operation and the equipment being replaced, so we do not give a single number — but the order of magnitude is known in the sector: energy is the largest item of operating cost.
Four levers efficiency
Pump according to demand
A fixed speed pump always rotates at its maximum, no matter what the process consumes. A variable speed pump adapts its regime to what the circuit needs at all times.
As in pumping the power grows very quickly with the speed, reducing the speed when full flow is not required cuts consumption significantly. It is the most important efficiency lever on a day-to-day basis.

Efficiency where cost weighs most
The SMART Series equipment incorporates a variable speed pump, proportional regulation of the cooling water, PID control with autotuning and insulation, with a contained noise level.
SMART Series and the operation cost
Variable speed pump (adjustable by pressure, flow or ΔT), proportional cooling valve, PID control with autotuning, thermal insulation and sound level < 70 dB.
The specific savings depend on the process, operating hours and the reference equipment; Efficiency acts on the largest part of the operating cost.
Common questions
What is the TCO of a temperature control unit?
The total cost of ownership: purchase, energy, cooling water, maintenance and shutdowns throughout the useful life. Energy is usually the dominant item.
What are the savings levers?
There is not just one: the real savings come from the combination. The variable speed pump adapts consumption to demand instead of always turning at maximum; the proportional cooling open only what is necessary and consume less water; a well-sized cooling system exchanges heat with less losses; he control PID con autotuning avoids unnecessary oscillations and starts; and a good insulation and design reduce losses to the environment. The pump is usually the heaviest on a day-to-day basis, but it is the assembly that cuts the bill.
How much do you save exactly?
It depends on the process, hours of operation and the equipment being replaced; That's why we don't give a single figure. Efficiency acts on the largest part of the operating cost.
Does efficiency compromise accuracy?
On the contrary: proportional control and PID with autotuning keep the temperature stable (±~0.5 °C) while reducing consumption.
