- Description
- Synopsis: This is a sources sought notice. All responsible sources may submit a capability statement, proposal, or quotation, which shall be considered by the agency. Description: NSRDEC is interested in replacing its current 3.6 BHP boiler/ 4.5 ton chiller arrangement used to heat/cool tooling on a large compression molding press. The boiler/chiller system is used to heat/cool matched metal tooling used in the production of thermoplastic and thermoset composite parts. There are two types of tooling the system will be used with, a single-zone tool and a dual-zone tool, both consisting of an upper and lower platen. The system design will need to address both tools; however, the tools will never be used together. The system consists of a boiler, a chiller, and a control system. The boiler is required to output 150 psi - 200 psi steam and should be between 7.5 BHP and 8.9 BHP. The boiler must have blow down and condensate return. The chiller is required to have a cooling capacity between 14 and 16 tons. All system components must be stainless steel and the system shall be programmable. The contractor shall design, source, and install the required system (plumbing/electrical work may have to be coordinated with NSRDEC's Public Works Department). The chiller must maintain 5 gpm of water at a maximum temperature of 70 degrees to the hydraulic pump on the press at all times. Compressed air is available to flush lines between heating and cooling cycles and should be incorporated into the system. The control system must be capable of controlling the following process: Case 1: Dual-zone tool Events 1 & 2: Heating/Soak In this portion of the process, the high temperature zones of the top and bottom platens will be heated with steam. Steam must be regulated individually for each platen up to 150 psi. We wish to control pressure as a function of time. For example, the process may call for 100 psi for 2 minutes, 50 psi for 1 minute, and then hold pressure at 40 psi for the remainder of the cycle. During this heating/process cycle the low temperature zones of the top and bottom platens will be cooled with water from the chiller. Water flow must be regulated individually for each platen up to one half the capacity of the chiller. We wish to control this as a function of temperature read from thermocouples either placed in platens or directly in part. Flow may need to be pulsed in order to maintain proper temperature gradient in platens. Event 3: Cooling When the soak portion of the process is completed, high temperature zones of the top and bottom platens will be cooled with water from chiller. Water flow must be regulated individually for each platen up to one half the capacity of the chiller. We wish to control flow as a function of temperature read from thermocouples placed in the platens. Water will also continue to be used to cool the low temperature zone of the top and bottom platens. Case 2: Single zone tool The process for the single zone tool is identical to the process described above for the dual-zone tool with the exception of the low temperature zone which should be blocked off during use of the single zone tool. The design should incorporate provisions for preventing flow of water to low temperature zone during use of this tool. The Government is conducting this market investigation to acquire information on the types and sizes of businesses that will be able to compete on future contracting actions, potential costs as well as delivery capabilities. Interested firms are requested to submit relevant information on their company within twenty eight (28) days following the publication of the RFI. Any relevant company background/experience, business category, costs, and any other information that the company believes demonstrates their value/ability to meet the aforementioned requirements should be included. In particular, address the following: 1. Company/Agency 2. Point of Contact a. Name: b. Email Address: c. Telephone Number: 3. Please describe the company's history in performing design, installation, and integration of temperature control systems with applicability to industrial processing. Approximately how many of the aforementioned systems have been designed, installed, and integrated and over what period of time? 4. What is your business type and size. This RFI is solely for information purposes and does not constitute a solicitation or the issuance thereof. Responses to this RFI are not offers and cannot be accepted by the Government to form a finding contract. Any information submitted will not be returned, and no payment will be made by the Government for such information. Respondents must be registered in the System for Award Management (SAM) and provide a DUNS number. Firms may register for SAM at https://www.sam.gov/portal/public/SAM/ Responses to this notice can be sent via email to Roberta.l.ciaramicoli.civ@mail.mil. Any technical questions regarding this RFI should be address to Jason Parker via email at: jason.c.parker3.civ@mail.mil
