Page 11: Introduction
Introduction Congratulations on your purchase of the EC-30C ultra-low cooler. We know from experi- ence that you surely will enjoy this reliable and durable M&C product. M&C is one of the premium and performance-driven companies in the business. With this in mind, our customers benefit from a number of significant advantages. -
Page 12: Product Overview
Product overview 4.1 Application The M&C ultra-low cooler EC-30C is used in the gas analysis technique to reduce the dew point of humid sample gases and to provide a stable and very low dew point. This elimi- nates condensate built-up and aerosol formation in the analyzer. -
Page 13: Principle
The micro processor-controlled electronics of the EC-30C in combination with the graphi- cal display, offers a high degree of functionality, convenience in use, and safe operation. The EC-30C is built for 24/7 hours of operating time. The cooling capacity of 130 kJ/h is constant, even under maximum allowed ambient temperature. - Page 14 The EC-30C switches automatically every 3 hours between the two deep freezer units. The deep freezer which is currently not in use, will be defrosted to prevent freezing of the heat exchanger and clogging of the gas lines. Upon special request, this cycle of 3 hours can be reduced directly at your facility by M&C personnel.

Page 21: Self-Monitoring During Operation
Over time the signs of aging of the Peltier elements increase gradually the value of the internal resistance. As a consequence the power necessary to keep the target temperature constant can not be supplied anymore. The projected capacity reserve compensates this unavoidable aging effect and maximizes the service life of the EC-30C. 7.4.2 Pre-warning messages If the capacity reserve has been exhausted up to a critical value, the unit will show a warn- ing message about the upcoming failure. -

The EC-30C connected to the LA gives an alarm signal which will be registered in the alarm and warning history. The cooler switches the alarm relay to stop the gas supply by either turning off the sample gas pump or triggering a solenoid shut off valve. -
Page 53: Gas Flow Sensor Fa 20 And Gas Flow Meter Fm 40 (Optional)
The gas flow sensor allows both internal and external mounting. In case of internal mounting of the FA20, it is necessary to mount into the EC-30C an addi- tional flow meter FM40 with a scale of 0 to 250 l/h. -
Page 54: Start-Up
Do not extract gas when the EC-30C is turned off or when the LED light is red! When the EC-30C is started, one of the gas lines through the deep-cooler is always open. The outlet status contact must be connected to an external sample gas pump or a valve in the sample gas line to protect the entire analysis system by immediately cutting off the gas supply in the event of error messages of the cooler. -

The pre-cooling unit PCU is cooling down to the target „ temperature +2 °C (+35.6 °F). Deep-cooling unit DCU 1 (green line) and deep-cooling unit DCU2 (purple line) are cooled passively by the pre-cooling unit.
- Page 58 DCU 1 reaches the target temperature of -30 °C (~-22 °F). EC-30C switches „ the gas flow to DCU 1. DCU 2 turns off for 20 minutes. From this point on the cooling stages of the EC-30C keep on repeating themselves starting with stage . Unlike the restart phase, stage will take a longer time period during the operation process.
