The E-TES 120 is built in the same housing as the E-TES 240 (current model). It will do everything the 240 model does, but at a slightly slower pace. The E-TES 120 has an average of a 20° heat rise, while the E-TES 240 has an average of a 31° heat rise. Remember that this heat is synergistic; that means that when heat in the room reaches 95°, the recommended temperature setting for the exhaust controller, the temperature coming out of the E-TES 120 would be 115°. Moreover, anytime you contain the heat under plastic or carpet for example, this slows the airflow passing across the heat coil giving it even a higher increase, possibly reaching 140° (a 45° heat rise) coming out the snout.

We are still waiting for E-TES to be listed in Xactimate, but hundreds of restorers are getting $250 to $300 per day for E-TES 240. We believe they will be able to get similar rates for the new E-TES 120.

E-TES 120 comes with two 50' 15 amp cords; each cord will use 14.6 amps in start up. Having an E-TES 120 now makes it easier than ever for restorers to use more than one E-TES at a time on a job.

You may be asking yourself why would a restorer buy a regular TES trailer unit with the new E-TES 120 now available?

The answer is power, heat, and income. Compared to the E-TES 120, the TES trailer unit and TEX boxes deliver more than double the heat out-put, utilize very little electricity, generate higher daily rents and dry the job in record time. If you purchased a TES trailer with five TEX boxes, you would get a 50° heat rise (average) out of each TEX without any electricity requirements other than the airmover. Five E-TES 120's would require 10 dedicated 15 amp breakers, plus an additional one for the airmovers while only providing about half the heat.

Part # MB1202, Contractor Price $2,195

One question that arises when contractors are considering Directed Heat Drying™ is: "Does the IICRC S500 support using this process?" The simple answer is "Yes!," however, you might want some proof.

This discussion will be a series, since there are so many references to discuss.

The following is based on research done by Scott Warrington. It references several sections of the S500.

What Do the Standards say about Heat Drying and TES?

Pages 7 – 88 of the S500 is the "Standard" section. This summarizes what is the "standard of care" in the water damage restoration industry. The standard not only recognizes every one of the principles of drying used by TES, it recognizes the science behind TES, but in many situations, heat based drying systems (also called thermal drying systems in the S500) using negative pressure along with dehumidification by exchange of indoor air with outdoor air is the RECOMMENDED method. When the standard uses the term "recommended" this is the advised or suggested method to meet the standard of care.

The standard section is followed on pages 89-317 by an expanded reference guide. The standard is taken from this reference guide.

Let’s look at several of the many examples that prove conclusively that S500 supports direct application of heat and TES. Numbering refers first to the page, then to the section and subsection where this information can be found.

P. 18 - 4.2.4.4: Temperature control is important to control evaporation rate. Temperature application, modification and control are important basic principles for safe, effective drying.

P. 20 - 6.1.1: "Restorers should manage airflow to exchange humid air from a space with more favorable air..." This is exactly how TES removes warm, moist air.

P. 39 - 9.10.8.4.4: When drying wood flooring attempt to reach target humidity of 45% or less. Ambient temperature may be increased to expedite both evaporation and dehumidification. This is precisely what TES does - increases the temperature to expedite evaporation.

P. 49 - 12.1.11: Ventilating the structure may be an effective way to reduce the build up of excess humidity. Of course, TES set-up normally uses ventilation to reduce humidity.

P. 51 - 12.1.20: Controlling airflow increases evaporation. Note the third bullet point – Means to increase the rate of evaporation include increasing air or surface temperature.

P. 52 - 12.1.22: "Controlling Temperature to Accelerate Evaporation - ...the temperature of the wet materials themselves impacts the rate of evaporation significantly. Water in its vapor phase (gas) has much higher energy than water in its liquid phase. Therefore significant energy is required for evaporation. ..."

P. 52 - 12.1.23: "Applying Heat Directly to Materials - ... thermal energy transfer and other systems employing direct heat application can be used to increase the temperature of wet materials.... Additional direct heat can accelerate drying of wet materials, especially, dense, less-permeable materials."
