Direct and Indirect Heating Systems

Since I have been blogging about portable heating systems I might as well keep it going. 

One question that keeps popping up when people talk about portable heating systems is

 Direct Fired and Indirect Fired Heaters. 

A Direct Fired Heater heats the air by a flame that is produced by burning some type of fuel. (Natural gas; Propane, Kerosene or Diesel)  Usually there is a fan to move the air through a tube or cylinder where this flame is contained.  These types of heaters are almost 100% efficient and therefore very cost effective.

An Indirect Fired Heater also heats air by a flame that is produced by burning some type of fuel. (Natural gas; Propane, Kerosene or Diesel)  There is a fan to move the air through a tube or cylinder where a heat exchanger is located.  This heat exchanger is where the flame is contained and has a port where the exhaust can be vented away from the area you are heating.  These types of heaters are not as efficient but are still very good.

The important thing to remember is you need to match the correct type of heater to your particlar application.

 

 



Temporary Power

Spyder Box and Cables

Now that Thanksgiving is behind us and the days are still getting shorter you might be thinking about temporary power for different applications.  Maybe you are in construction or maybe you are opening a Christmas Tree lot for the upcoming holidays.  Both of these projects need temporary power.  The key is to have safe and reliable power to run the equipment and / or lights.  You will need and a way to connect all this equipment and that is where a Temporary Power Box that is UL listed for use in wet and damp locations comes in.

There are 2-types of Temporary Power Boxes.  They both are rated the same for voltage / current and you can order either type of connector depending on your cables.  Where the difference comes in to play is the amount of circuit breakers.  The 1st type will only have 3 breakers and the 2nd type will have 6 or a breaker for each outlet.   

If you don't already have cables to connect to your Temporary Power Box you have a couple types to choose from.  Both are either 50 feet or 100 feet in length.
The 1st is a Vinyl temporary power cord rated from -40 degrees to 140 degrees Fahrenheit.  The wire type is STOW (Service, Thermoplastic jacket, Oil resistant jacket, Weather resistant).  Hard service Thermoplastic cord which will deform under extreme pressure or heat.  STOW features an oil resistant jacket and is for indoor/outdoor use with heavy tools, equipment, portable lights and power extensions. 

The 2nd type of temporary power cord is a SEOW (Service, Elastomer jacket Oil resistant jacket, Weather resistant)  Features a Thermoplastic Elastomer jacket and insulation, which offer exceptional low temperature capabilities.  SEOW has an oil resistant jacket and is water resistant and extremely lightweight.  SEOW is suitable for outdoor use in industrial applications with construction tools and other electrical equipment, but is not recommended for contact with hot surfaces.  This cable is rated from -58 degrees to 228 degrees Fahrenheit.



Temporary Heating Systems

Temporary Heat for the Construction Industry, Special Events or Emergency Services

Hytopz takes the time to customize your temporary heating system so you know that it will work for whatever your application might be.  We can size and layout your project for maximum effectiveness.  Being able to accurately estimate the energy consumption will help you quote your actual costs for an event or job.

Estimated Heating Load
The projected heating load for a project is based on maintaining a design temperature that the customer requests.  We take into account the transmission heat loss of the walls and roof from conduction and the heat loss due to infiltrations of outside air through cracks, pores, and other openings in the structure.  The load is calculated using project specific data, project measurements and regional temperature data from the National Oceanographic and Atmospheric Administration (NOAA).

Air Ventilation Changes per Hour
To adequately dry a structure and exhaust any dirty air we always recommend that you change the inside air of the building 1.2 times per hour.  This is one of the most important aspects of a heating system in a building under construction.  If the air flow is not replaced with fresh air you can have a multitude of problems.  Uncontrolled moisture indoors can cause major damage to the building structure, as well as to furnishings and to finish materials like floors, walls and ceilings.  Uncontrolled moisture can trigger mold growth which not only damages the facility, but can lead to health and performance problems for construction workers.

Fuel Consumption
Calculating the fuel consumption varies with the type of fuel/energy.  Formulas for each fuel type will be either in gallons (propane, diesel), Therms (natural gas) or kilowatts (electricity).  When calculating fuel consumption we take into account the outside average temperature during a given heating period and the average temperature differential.

Safety Training

Safety is our number 1 priority here at Hytopz

We are in the business to keep our customers safe.  We want to ensure that the men and women using Scaffolding, Telehandlers and Aerial Work Platforms (Boom lifts - Scissor lifts) can do their jobs efficiently and safely.  The more people understand the equipment they are using the better they can do their jobs.

Accidents and incidents are preventable.  Safety training in the Spokane area for Scaffolding, Telehandlers and Aerial Work Platforms is scheduled 4 times a year. 

The class outline for Telehandlers & Aerial Work Platforms includes:

• Safety Precautions
• User Responsibilities
• Machine Preparation & Inspection
• Machine Operation
• Towing
• Emergency Procedures
• Machine Specification & Operator Maintenance
• Course time - 4 hours

After passing a written test and hands-on practical, the student will be issued a card valid for 3-years that meets both OSHA regulations and ANSI/SIA standards.

Scaffold orientation is designed to orient the worker to the "Code of Safe Practices" developed for the industry by the Scaffold and Access Industry Association, Inc. (SAIA).  The class is intended to address some of the many practices and conditions encountered in the use of steel frame scaffolding.  Upon completion of the safety training the worker will be able to identify different types of scaffolding and the hazards associated in the workplace.
