Refrigeration systems
Usage (kWh) savings of 10% to 25%
No penalty system
No change to pre-existing operating criteria
No impact on air conditioned space

ESM ™ Key Features
Retro-fittable product with minimal field wiring or plant down time
Self-learning - requires no manual adjustment
Always fails to safe
Certified product
CE Certified
UL Certified
Remote communications and control

The ESM ECO³™ Product Overview

ECO³™ Features
Two models:
Single Channel, for use with a single compressor
Dual Channel, for use with two compressors cooling the same controlled space
Reduces compressor run times
Usage (kWh) savings averaging 20%
Interfaces with existing controls
No risk to current equipment or effect on manufacturer’s warranty
Maintains temperature performance
Optimizes the efficiency of the cooling & heating cycles on compressor driven heat pump units
The ECO 3 ™ is an economical, small-scale application of the same technology used in the ESM™.

ECO³™ Features
Displays kWh savings
Allows bypass- auto returns to savings when bypass complete
Smartcool proprietary software
Multiple cable diameter sealed entry
IP64 rated for outdoor installations
Simple wall mount and product installation

Compatibility With Control Systems
Compatible with all known control systems since it complements, but does not replace the primary controls
25,000 units installed world wide on many different control platforms
ESM™ has RS 485 & RS 232 communication ports which allow for networking of all units on site & connection with PC via LAN or Modem

NO Impact on existing equipment warranties
Complies with compressor manufacturers specifications for cycling rates
Low voltage product with a fuse to protect existing equipment
Always fails to safe
Standards compliance
Quality Assurance: Complies with ISO9001
North America: Complies UL 916 & ULC 22.2 No.205-M1983
Europe (CE): Complies with EN60730 (IEC 730) & EN60950:2000
Complies with EMC directive EN55022, EN55024, 89/336/EEC & 93/68/EEC
Australia: Complies with AS2064, AS3100 & AS3260
Impact on Existing Equipment Warranties

So… How do the ESM TM & ECO 3TM achieve savings?

COMPRESSOR OPTIMIZATION
Designed to work with the existing aircon and refrigeration equipment, along with the current control methodology, to reduce energy consumption
When a call for cooling comes from the existing controller, the advanced control module takes over to determine when and for how long each compressor or unloader will run
This advanced control technology enable the compressor to maximize the rate of heat removal by optimizing the natural physical properties of the compressor operating cycle

Background
The table to the right, shows a typical chiller compressor capacity chart for a nominal 40 kWh heat load, showing the time & energy taken per degree of temp. reduction
Reducing from 6° to 5°C takes 14.4 minutes and 3.57 kWh
The last degree of pull down uses almost twice the energy and time
The example above, uses a +(-) 2.5° C suction temperature differential

Background (cont’d)
The chart to the right illustrates the percentage of energy used per degree.
The last degree of pull down used 28% of the total energy for the cycle
Unfortunately, this increases the mid point temperature from 7.5°C to 8°C.
