For what an attention should be paid ?
Decision on optimal radiators selection is not contribution to energetic resources careful consumption and reduction of environment pollution only , but , first of all , the measurable economical benefits for investors.
Therefore it should be checked:
- Is the offer honest , has it the full delivery scope , and complete system solutions ?
- Are all tenderers the same conceptional assumptions use ( project , the same installed power , required temperatures ) ?
- Proposed devices , are they the up-to-date solution of halls heating ?
- Proposed radiators , are they capable for high objects heating e.g. till 10 m , till 20 m , where high equipment radiation effectiveness is required ?
- Are radiators in low compartments installed ( 3 - 5 m ) capable for suitable heat comfort assure ( do not excessively heat the workers head ) it means , is equipment power on 1 running meter amounts e.g. 1 kW , and what is the noise level of radiator work ?
- Are radiators insulated ?
- Which ones materials are used for radiators construction ?
- Are devices equipped with independent gas systems , or with common systems for many burners ?
- Is it air drawn outside the hall , or is it inside hall absorbed only ?
- Are all tenderers equipment assembling and putting in motion offer ?
- Combustion gas emission how high is it ?
- Are they known real equipment exploitation costs ?
- Which ones are the costs of electrical and gas installations , as well as the number of roof's gangways in particular cases of other tenderers ?
- Are proposed equipments fulfill environment protection requirements ?
